Second anec-data point, I'm logged in via TBB right now too. I get captcha-ed when I first hot the site over TOR, but it works "as expected" once past that.
(It wouldn't surprise me too much if some TOR exits end up filtered transiently due to abuse - it might be worth refreshing your circuit (or waiting ~10mins for the TBB to do it as usual))
