Hmm, it seems that you're correct. Something (probably in the schedd) has been changed to affect this. Actually, my testing reveals that, at least for ENV, $$(var) seems completely broken, but it does seem to work, for example, with ARGUMENTS. :-( We need to look into this ...
Thanks again for your help, Chris.
