[Dovecot] sieve :regex problem

Hello, I have dovecot 1.1.1 with dovecot-sieve-1.1.5 and managesieve 0.10.3. Everything is working, with exeption of this filter:

if header :comparator "i;ascii-casemap" :regex "X-Spam-Score" ".*\+\+\+\+" { fileinto "Spamq"; stop; }

Which I think should match only messages with ++++ somewhere in their X-Spam-Score header - but matches everything (this is filter generated by ingo fom horde.org framework). Can someone please tell me where the problem really is?
