If I were you I would experiment with forwarding. Maybe a few new lines will do the job.
Code:
forward .daemonforums.org .
forward *.daemonforums.org . # I do not know if this is semantically correct
forward daemonforums.org .
Keep in mind that privoxy usually do the last matching job, so forwarding to Tor client should be first and then cancelling forwarding to daemonforums by dot ".".
