Search and replace with superscript for Word

Hi, this should be simple but I just can’t figure it out. I’m doing a search and replace like:

tell application "Microsoft Word"
	set findRange to find object of selection
	tell findRange
		execute find find text "®" replace with "®" 
		replace  replace all
	end tell
end tell

and I just want have the replace be superscripted.

Thanks,
