No problem. For others who are interested in using SpamAssassin to tag
or even reject emails with SPF-Failures: Create a new textfile in
/etc/mail/spamassasssin/ and give it any name you like. But it must end
with *.cf. Example: spf.cf
Into that textfile insert the following two lines:
score SPF_FAIL 10.0
score SPF_SOFTFAIL 5.0
You might want to adjust the scores to your liking. Then restart
SpamAssassin and you're good to go.

Yes, that is a worthwhile addition and I will add it to the next release
of the AV-SPAM.
