Resetting preferences indesign

I am still looking for a solution to resetting some specific preferences in InDesign.
This script does not generate any errors, and most of the items are functional, EXCEPT for the pasteboard preferences items. Neither command changes the margins or the match preview preferences. Any ideas??
