[Mimedefang] spamassassin scores ignored in sa-mimedefang.cf

[Christoph Lehmann]

I like to use different configuration files for authenticated and 
non-authenticated users.

Inside MD i call SA like

($hits, $req, $names, $report) = 
spam_assassin_check('/etc/mail/sa-mimedefang.cf');

or

($hits, $req, $names, $report) = 
spam_assassin_check('/etc/mail/sa-mimedefang-authuser.cf');

My sa-mimedefang.cf contains

score URIBL_BLACK 5.0 5.0 5.0 5.0
score URIBL_DBL_SPAM 5.0 5.0 5.0 5.0
skip_rbl_checks 0
dns_available 1

Debugging doesn't show warnings...

Why are my given scores ignored?

Thanks for your help.
