I'm interested in the topic, perhaps not to wrangle over it but at
least to have a standard way of identifying the filter program(s)
being used.  If there's already something in practical use, or some
current thinking on the subject, so much the better.  I was thinking
mostly of a meaningless "filtered-by" sort of label, but you mention a
score, for which there might be a more structured header or suite of
headers.  Personally I think that with a variety of ways of marking
scores (or in fact even having the concept of a "score"), it would be
hard to specify the a particular structure here.  Plus you might have
a message passing through multiple filters, each of which would want
to place its mark on the message without disturbing other such
marks (so you'd need a tuple of at least {agent, location, assessment}).

Anyway I don't mean to go off on details here.  I am interested should
it be discussed somewhere.
