Duh. Ok that seems to be the case, and a definate reason not to have
site wide Bayesian filtering turned on. [And another reason for CanIT]
Turning off the site-wide Bayesian lines brought the scores in line with
the other side.

The second problem I was having is that 2 upstream sites are using
mimedefang+spamassassin in their systems and for some reason I was
seeing their score printed versus my own. When I commented out the line

                # action_delete_header("X-Spam-Score");
