I reread the procmailsc man page and changed the scoring accordingly
to:

:0 B
* 1000^0 H ?? ^\/(From|Subject):.*Condition
* 1000^0 ()\/Condition

That still did not help!

No, but to expand upon David's answer, if you shortcircut all the
scoring, it will:

:0:
*  9876543210^0 ^\/(From|Subject):.*Condition1
*  9876543210^0 B ?? ()\/Condition2
* -9876543210^0
* ! From:.*(Person1|Person2)
| (formail -z ...)

That way if either of the first two conditions match, procmail skip all
the rest of the scoring conditions, including the third with its
infimum weight.  If neither of the first two conditions matches then
the third will cause procmail to skip the remaining conditions and fail
the entire recipe.

I suppose that it would be more efficient to reverse things here.

It's all done with pointers, so the cost is trivial.  For something
that cheap, readability is probably the deciding factor.
