Applescript Folder Action not working - macos

Question

I wrote an Applescript that would monitor a folder for new input. On receiving the new item, it would open iTunes, create a playlist and add the new files into the playlist. However, when I attach the script as a Folder Action via Folder Action Setup and add a new item, nothing happens. I have placed the script inside /Library/Scripts/Folder Action Scripts as well as ~/Library/Scripts/Folder Action Scripts but it still doesn't fire. Here is my code below:
global album_name
global artist_album
on adding folder items to this_folder after receiving added_items
--get the name of the added folder
repeat with x in added_items
copy name of x as string to playlist_name
set AppleScript's text item delimeters to "-"
set delimited_playlist_name to every text item of playlist_name
set artist_name to text item 1 of delimited_playlist_name
set album_name to text item 2 of delimited_playlist_name
set AppleScript's text item delimeters to ""
end repeat
tell "Finder" to activate "iTunes"
tell application "iTunes"
if not (exists playlist album_name) then
--make iTunes playlist
make playlist with properties {name:album_name}
--add the tracks to the iTunes playlist
repeat with song in playlist_name
add song to playlist album_name
set album of song to album_name
set artist of song to artist_name
set comment of song to ""
set composer of song to ""
set grouping of song to ""
set description of song to ""
set long description of song to ""
set (volume adjustment) of song to 100
end repeat
set view of browser window to album_name
end if
end tell
end adding folder items to
I'm running Mac OS 10.8.4

In the future
Test your code in the Applescript Editor, it helps a lot :)
If you dont use Applescript Editor, to get useful messages, use display dialog entries throughout your code to see how far it goes and what is going on.
So, assuming that the problem is with your code, I rewrote it as an simple Applescript and got it to work on my Snow Leopard (10.6.8) system.
It also runs ok from inside Automator as a Folder Action with the code in a Run Applescript Action item. Once saved from inside Automator it did activate when new files were added to the folder and run ok.
PS: Since you didn't provide any details, I had to guesstimate from your code what you were trying to do. It is far from optimal but it will get you going...

# remove this line for Applscript Action in Automator...
set input to (choose file with multiple selections allowed)
set playlist_name to {}
#display dialog "Delimeter set to -"
set AppleScript's text item delimiters to "-"
repeat with x in input
#display dialog "Item: " & (x as text)
tell application "Finder"
set fl to name of x
display dialog "Filename: " & fl
end tell
# bring back focus to the editor ## TESTING ONLY
activate me
# append item to the list
copy (fl as text) to the end of playlist_name
display dialog "Playlist count: " & length of playlist_name
set artist_name to text item 1 of fl
display dialog "Artist: " & artist_name
set album_name to text item 2 of fl
display dialog "Album: " & album_name
end repeat
#display dialog "Activating iTunes..."
#activate "iTunes"
#display dialog "iTunes activated!"
tell application "iTunes"
if not (exists playlist album_name) then
display dialog "Making new playlist: " & album_name
make playlist with properties {name:album_name}
display dialog "Changing view..."
set view of browser window 1 to playlist album_name
# add the tracks to the iTunes playlist
repeat with song in input
