It's probably not related to scoring but to 3.22's bug of a sticky H 
flag.  Once you have an H on a flag line in 3.22, H is on until procmail 
exits, and only  B ??  on a specific condition line can make it apply to 
only the body.

H without B is the default; you don't need it.  Because of that H, the B 
here is misinterpreted as HB:

so it counts all the lines in the entire message.

It also works if you specify  B ??  on the second and third conditions 
of the latter recipe; that evades the sticky-H effect.

Separately, one wonders why you're using the -b option to formail when
it's filtering only the head.

Because then you aren't setting the sticky H flag.
