Why would ``x.len()`` be any more convenient than ``len(x)``? Your
preference here seems pretty arbitrary.

Use sorted():
key = ','.join(sorted(word.lower().strip()))

Get Python 2.5 and use collections.defaultdict:
Python 2.5a2 (trunk:46491M, May 27 2006, 14:43:55) [MSC v.1310 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import collections
>>> d = collections.defaultdict(int)
>>> d['a'] += 5
>>> d['b'] += 2
>>> d
defaultdict(<type 'int'>, {'a': 5, 'b': 2})
