I'm merging a fresh orders.php file from 1.3.9h with Edit orders core edits using Winmerge.

I've read here that there are three edits to orders.php but I'm seeing a difference in the files and fear merging the change when it is not notated to be Edit orders specific is part of my problem with my install.

Here is the original orders.php section about line 550..and i did a search here for class="dataTableHeadingContent with no results.

Code:
<tr>
        <td class="main">
<table border="1" cellspacing="0" cellpadding="5">
          <tr>
            <td class="smallText" align="center"><strong><?php echo TABLE_HEADING_DATE_ADDED; ?></strong></td>
            <td class="smallText" align="center"><strong><?php echo TABLE_HEADING_CUSTOMER_NOTIFIED; ?></strong></td>

            <td class="smallText" align="center"><strong><?php echo TABLE_HEADING_STATUS; ?></strong></td>
            <td class="smallText" align="center"><strong><?php echo TABLE_HEADING_COMMENTS; ?></strong></td>
          </tr>
that same section in the edit orders version without any notation it is edit orders specific. Question: should this take the place of the above?:

Code:
<tr>
        <td class="main" valign="top">
	<table border="1" cellspacing="0" cellpadding="5" width="60%">
          <tr class="dataTableHeadingRow">
            <td class="dataTableHeadingContent smallText" valign="top"  width="21%"><strong><?php echo TABLE_HEADING_DATE_ADDED; ?></strong></td>
            <td class="dataTableHeadingContent smallText" align="center" valign="top" width="18%"><strong><?php echo TABLE_HEADING_CUSTOMER_NOTIFIED; 
?></strong></td>
            <td class="dataTableHeadingContent smallText" valign="top" width="17%"><strong><?php echo TABLE_HEADING_STATUS; ?></strong></td>
            <td class="dataTableHeadingContent smallText" valign="top" width="44%">
<strong><?php echo TABLE_HEADING_COMMENTS; ?></strong></td>
          </tr>
