Cover art in WMP11 Front Cover or "User defined"

I have a weird issue. I use mp3tag to tag all my files. I apply most changes by a set of actions I'm running for each album. I have one action that import folder.jpg from the directory the mp3 is stored in an add the cover to the mp3 files Cover tag.

In WMP11 some covers are classified as "Front Cover" and others as "User defined".
The only difference to me seems to be that if folder.jpg is dpi=72 then it's "Front Cover". If the dpi=96 then classification is "User defined".

It's of course also possible that all cases I have with "User defined" classification is from an earlier version of mp3tag.

Is there any smart way I can scan my files and ensure that Covers are classified as "Front Cover"?
