I'm doing something similar, using bogofilter to cross-check SA scoring. 
Just make sure you add a "bayes_ignore_header X-MessageWall-Score" to 
your SA config if you're using bayes, lest it learn to associate that 
header (regardless of score) with spam.

Er, hmm. How downright clever of you! I pass incoming messages through 
virus scanning and bayes scripts before spamassassin, but hadn't thought 
about letting good ol' spamassassin do all that hard math stuff for me. 
And it opens up possibilities with metas. Not to mention simplifying 
procmailrc, and scoring recipes.

Good stuff.
