I have modified magento extension for tier pricing and added three text fields in app->design->adminhtml->default->default->catalog->product->edit->price->tier.phtml file.
Data from three new field successfully inserted into table catalog_product_entity_tier_price.
Data is also visible on frontend. But problem is that in tier box price inserted data and field mismatched
<table>
<thead>
<tr class="headings">
<th>Website</th>
<th>Customer Group</th>
<th>Qty</th>
<th>Custom_field_1</th>
<th>Custom_field_2</th>
<th>Price</th>
<th>Custom_field_3</th>
<th>Action</th>
</thead>
</tr>
<tr>
<td>Showing Correct</td>
<td>Showing Correct</td>
<td>Showing Correct</td>
<td>Showing Custom_field_2</td>
<td>Showing Custom_field_3</td>
<td>Showing Correct</td>
<td>undefined</td>
<td> </td>
</tr>
</table>
<p> </p>
<p> </p>
<b>And javascript code is</b>
<script type="text/javascript">
var tierPriceRowTemplate = '<tr>'
+ ' <small class="nobr"><?php echo Mage::helper("catalog")->__("and above")?></small></td>'
+ '<td><input class="<?php echo $_htmlClass ?> Custom_field_1" type="text" name="<?php echo $_htmlName ?>[{{index}}][Custom_field_1]" value="{{Custom_field_1}}"

Problem Solved: Problem was in jquery code.
Please check my edited code
if(arguments.length >=8) {
data.website_id = arguments[0];
data.group = arguments[1];
data.qty = arguments[2];
data.product_type = arguments[3]
data.ourprice = arguments[4];
data.price = arguments[5];
data.links = arguments[6];
data.readOnly = arguments[7];
}
if (arguments.length == 9) {
data.readOnly = arguments[8];
}
Element.insert($('<?php echo $_htmlId ?>_container'), {
bottom : this.template.evaluate(data)
});
$('tier_price_row_' + data.index + '_cust_group').value = data.group;
$('tier_price_row_' + data.index + '_website').value = data.website_id;
