[Fuego] [PATCH 7/8] Fix TypeError: sort() takes no positional arguments in python3

From: sireesha <[email protected]>

Transform an old-style comparison function to a key function.
use functools.cmp_to_key(func) with sort() function to fix the issue.
This change is compatible with python2 and python3.
