Touche'!

For what it's worth, I spoke with the guy who did the code and he indicated that none of the code he sent checks for admin/etc. It uses variables already there in the template code. Therefore, it's probably some sort of setting that I'm overlooking.
Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<plugins>
<plugin active="1" executionorder="5" product="vbulletin">
<title>Tip Ratio: Determine ratio</title>
<hookname>showthread_postbit_create</hookname>
<phpcode><![CDATA[$post['tipratio'] = round(($post['reputation'] / $post['posts']) * 100, 2);]]></phpcode>
</plugin>
<plugin active="1" executionorder="5" product="vbulletin">
<title>Tip Ratio: Add to template</title>
<hookname>showthread_post_start</hookname>
<phpcode><![CDATA[$vbulletin->templatecache['postbit_legacy'] = str_replace(
'\' . $template_hook[\'postbit_userinfo_right_after_posts\'] . \'',
'<dt>Tip Ratio</dt> <dd>\' . $post[\'tipratio\'] . \'%</dd>' . "\n" . '\' . $template_hook[\'postbit_userinfo_right_after_posts\'] . \'',
$vbulletin->templatecache['postbit_legacy']
);
$vbulletin->templatecache['postbit'] = str_replace(
'\' . $template_hook[\'postbit_userinfo_right_after_posts\'] . \'',
'<dt>Tip Ratio</dt> <dd>\' . $post[\'tipratio\'] . \'%</dd>' . "\n" . '\' . $template_hook[\'postbit_userinfo_right_after_posts\'] . \'',
$vbulletin->templatecache['postbit']
);]]></phpcode>
</plugin>
</plugins>

Here is the code in the postbit_legacy:
Code:
<vb:if condition="$post['joindate']"><dt>{vb:rawphrase join_date}</dt> <dd>{vb:raw post.joindate}</dd></vb:if>

<vb:if condition="$show['reputation']"><dt>My Tip Rep</dt> <dd>{vb:raw post.reputation}</dd></vb:if>
<vb:if condition="$post['age']"><dt>{vb:rawphrase age}</dt> <dd>{vb:raw post.age}</dd></vb:if>
<dt>{vb:rawphrase 'posts'}</dt> <dd>{vb:raw post.posts}
</dd>
