[jQuery] Not working for me in IE7, but works in IE8

I just tried a simple alternate colored table rows in jQuery 1.3.2.
It works fine in the good browsers, works in IE8, but doesn't in IE7.
I thought jQuery worked in IE7. I'm using the IE multitester suite.
(It doesn't work in IE6 either, but I stopped thinking about IE6
except in the "dead" sense ;')

Here's the site - it's a table of religious days on the front page.

Here's the code - very basic. The alt class gives a light green color
in IE8. I thought maybe my testing suite is off so I'd like to know if
anyone else sees a lack of color bands in IE7.

jQuery(document).ready(function() {
jQuery('tr:odd').addClass('alt');
});

This is a Joomla site, and since Joomla has an ancient version of
MooTools embedded, I'm using jQuery instead of $ in compatibility mode.
