The spamassassin list has been tracking an issue where a new rule made it 
out of the testbox accidentally, which lowers scores on a lot of spam.  It 
wasn't in the sample you provided, but the rule name is BAYES_999 - it 
catches mail that the bayes filter thinks is 99.9-100% sure to be spam.  As 
it got promoted prematurely, it's showing with a score of 1.0.  (The 
default.)  It's probably a part of your problem.

A fix should be in the rules update today or tomorrow - or you can rescore 
it to the same as BAYES_99 (someplace in the 3 range by default, I 
believe).  That's what used to catch that mail: it used to mean 99-100%, 
and now means 99-99.9%.

More info can be found in the mailing list archives for the spamassassin 
list.
