I forgot to mention. As far as I can remember my script doesn't use ICE at all and doesn't modify the edge cluster. It just selects edges, and the [hard] button automatically deletes the edge cluster. (I've never used it after creating hard edges).
Maybe doing an ICE version and manipulating the selection or cluster from a script would be faster than my script. Even with Python.
