I have been having the exact same problem.  Interestingly, the use of 
rules in defining smart mailboxes seems to be fine, and at least some of 
my old rules are working. I just cannot seem to get a new rule to work.

I have seen anomalies in development of rules, too -- I was trying to 
build them using tagging as the action (so I could easily see the effect 
of a rule), I would add and then delete conjuncts to a rule and this 
change was not idempotent: the rules would stop working with the new 
conjunct, but would not start working again when I deleted it.

I have a vague memory of Benny saying there was some way to debug the 
rules (by enabling some kind of MM logging to the screen), but I have 
forgotten how to do it. 😢 I think I had to toggle some preference and 
then start MailMate from the command line...
