If you make an alias to your iTunes Scripts folder (~/Library/iTunes/Scripts) and drop it in your user's Scripts folder (~/Library/Scripts), then as long as you have the system-wide Scripts Menu enabled, you'll be able to access all of your iTunes scripts (including ones that don't show up in iTunes 9.0.2), and any you might add, from the system Scripts Menu.
When Apple fixes the bug, simply delete the alias from your ~/Library/Scripts folder (or forget about it, as there's no harm or duplicates, and you'll be able to access the scripts from two places).
