It's trivial for a spammer to set up SPF on a throw-away domain and
thus waltz thru that kind of filtering.
You are spot on, spammers are much more competent in setting up spf/dkim
than most of legit mail administrators.
I personally score spf/dkim that passes at 0 and only penalize the fails

If you set those to 0, then you could be disabling many other helpful
meta rules that use them. It is recommended to set them to a very small
non-zero number as others have said:
score SPF_PASS -0.001
score SPF_HELO_PASS -0.001
