Use the key= argument to the sorted() builtin function
sorted_nodes = sorted(Ntop, key=get_node_x)
(For a list of reasonable size, that's fine. For a giant list, this could
be written more efficiently, although less readable)

AFAIK those are plain lists. You can try:
py> print type(Ntop)
and see what happens. If you don't get <type 'list'>, try with:
to see the chain of base classes.
