There are several possible causes of the discrepancy:

* You are running an old version, the site you used probably is using
the latest, 3.3.1 (with the latest rule sets).

* The scores come from the rule sets, which are updated periodically...
do you use sa-update?

* You could have changed scores locally, but you said you are using
defaults, so I only mention it for reference.
