Scipts not showing up under WINE on a Mac

I recently got a Mac computer and I am running the latest mp3tag under WINE. It is working great but when I add new Web Source Scripts they do not show up, however the default ones that came with mp3tag are there and work fine. Anyone else had this issue or know what is going on?

FYI: Specifically, I am attempting to get the lastfm genre script working. It works find on my WinXP laptop but I'd like to be able to use it from my Mac.
