Out of curiosity, any reason that you're including the index?  I'd 
have expected to just do

     L2 = [(d[key], d) for d in L]
     L2.sort()
     L = [d for (v, d) in L2]

I suppose that your version has the virtue that, if the sortkey value 
is equal, items retain the order that they were in the original list, 
whereas my version will sort them into an essentially arbitrary order. 
  Is there anything else that I'm missing here?
