Tablelist is a megawidget of other core Tk widgets, tktable is a pure C-based widget.

Not sure if that is a real cause, or just varies the trigger slightly.  As you noted that ActiveTcl has this working, I suspect it is a regular core bug that has been addressed since 8.5.7 that ships with Snow Leopard.  The problem with OS X (and similar OS vendors) is that you can't rely on them to update the language core you rely on.  With the release of Snow Leopard, this was the first Cocoa-based release of Tk in the wild, so it in particular had several issues.
