[Zope] sort order for tree display?

I'm still experimenting with ZOPE and the FAQ tool, which uses the 'tree' display widget. When I add a category or a FAQ entry, these items seem to appear in reverse order of the order I added them. The FAQ widget index_html DTML contains the line: <!--#tree sort=isCategory--> On what basis are the categories sorted? By name of the object's folder? Is there anyway to get the entries sorted in the order they were entered? Thanks much!
