Another possible solution, using a slightly different route:
best = max([x[-1] for x in l])
print [x for x in l if x[-1] == best]
Line one: Find the max value for the last item in each of the tuples.
Line two: Get the tuple that has that max value.
Slightly less efficient, since it uses two list comprehensions, and thus
traverses the lists twice, but easier to understand at first glance, imho.
