I ran into this, too.  You have to make a "dummy" resource, and then you
access the results with the "data" field.  Here's the function I use to
get the text on the clipboard:

import Res
import Scrap

def scrapString():
    TheScrap = Res.Resource("")
    Scrap.GetScrap(TheScrap, 'TEXT')
    return TheScrap.data

There's probably a better way to do this, but this has worked for me so
far.
