I suggest adding a metarule to combine two blacklists or two whitelists, and see what the existing score-generation procedure gives it. If my idea is confused, then most such metarules might have near-zero scores. If one ends up with A=2 B=4 and A_and_B getting -1, that validates the concept.
I'd first verify the assumption that the score generator will generate negative scores. I don't know that it does not, but there are only 56 rules with negative scores and almost all look manually assigned. I suspect that automatic generation of negative scores is intentionally suppressed to inadvertently avoid opening up "magical bypass" rules for spammers.
If this is indeed the case, then maybe we need a tflags option to tell the score generator "this rule's score is allowed to go negative".
