Could there be just a slight chance of a possibility that a Dmoz listing counts "twice"?

Once the link from DMOZ and once from the Google directory?
(they show both on the back-links - probably just wishfull thinking on my side though)

The "theme" thing, both Fathom and Brett are talking about, could be something.
If your site has multiple listings within DMOZ, hopefully Google will take into consideration more cats then what seems to be the just the oldest one, when you type in a search for "mysite" in Google.
