Did you have a look at this thread:

> Hi, How do I permanently change 'MediaType' for iTunes? e.g. I want change some MP3 files (not MP4) mediatype to 'audiobook' instead of 'music' in iTuens, but I want these property to stay with the files, and I don't need to reDo them next time on other itunes from a different computer. Note: MP3 files are stored on a network drive and are shared.

It looks as though there are many more types for mediatype:  
Movie, Normal, Audiobook, Music Video, Short Film, TV Show, Ringtone

And: these categories are only valid for MP4 files anyway (which in a way has been indicated by you as you want to delete the field from mp3s)  
You could create an action of the type "Format value" for MEDIATYPE  
Format string: `$ifgreater($strstr(%_tag%,MP4),0,Music Video,)`
