Default [Q] Nook Simple Touch - Cleaning up Google "My Apps" List

Tried out some apps installed from Google Play onto my NookManager root Nook Simple Touch, but after I uninstalled them, I can't get rid of the entries on the "My Apps" list at Google Play. It seems that function came available when Android Market updated to version 3.9.x of Google Play that is not back-compatible with Eclair 2.1. Any suggestions how to clean up the list when my Android device is the NST?
