Strange Score

[Christopher Mills]

Look at this,

X-Spam-Checker-Version: SpamAssassin 3.1.4 (2006-07-25) on
    chrysalis.chrysalishosting.com
X-Spam-Level: ****
X-Spam-Status: No, score= 4.3 required=5.0 tests=BAYES_50,HG_HORMONE,
    HTML_40_50,HTML_MESSAGE,J_CHICKENPOX_43,J_CHICKENPOX_55,OFFER,
    SPECIAL_OFFER,UNPARSEABLE_RELAY autolearn=no version=3.1.4
Received: from localhost by chrysalis.chrysalishosting.com
    with SpamAssassin (version 3.1.4);

The score is off. It flagged the message as {Spam?} as it should, because the required score is 5.
XSpam level shows 5 stars, but the line below says it got a spam score of 4.3

What gives?
