watermarking rules...

Looking at the settings you can indeed set a score to add to SA score

# If the message has an invalid watermark and no sender address, then it
# is a delivery error (DSN) for a message which didn't come from us.
# Delivery errors have no sender address.
# So we probably want to treat it as spam, or high-scoring spam.
# This option can take one of 4 values:
#         "spam",
#         "high-scoring spam",
#         "nothing" or
#         a number greater than 0.
# If it is set to a number, then that is added to the message's spam score
# and it's spam status is updated accordingly.
# If you set it to "nothing" then there probably isn't much
# point in checking watermarks at all. But it could still be useful in
# rulesets and Custom Functions.
# This can also be the filename of a ruleset.
Treat Invalid Watermarks With No Sender as Spam = high-scoring spam
