Tablesorter digit problem with Heroku

Tablesorter digit problem with Heroku

I've tried two methods for having the tablesorter plugin
(tablesorter.com) sort as digits:
1) Inline:
<table id="teams_table" class="tablesorter {sorter: 'digit'}"
border="1" rules="all" frame="box" cellpadding="2">
2) In my jquery file:
$("#teams_table").tablesorter({
sortList: [[3,1],[6,1],[4,1],[9,1],[7,1]],
sorter: 'digit'
});
Both methods work fine on my local Mongrel server, but neither work
when pushed out to Heroku. The console shows no errors. If anyone
has an idea, I'd appreciate hearing it.
