First paste the following into the Script Editor and save it to the Word Scripts folder in your Office 2008 identity:

tell application "/Applications/Microsoft Office 2008/Microsoft Word.app"
	tell selection
		try
			set theClip to Unicode text of (the clipboard as record)
			type text text theClip
		end try
	end tell
end tell

Then use System Preferences to set a keyboard command for the resulting script menu item. A kludge, but seems to work. I found this here.
