This is addressed in the PEP 3101:
"""
The rules for parsing an item key are very simple.
If it starts with a digit, then it is treated as a number, otherwise
it is used as a string.
""" http://www.python.org/dev/peps/pep-3101/
If current implementation does something more involved, I would say it is a bug.
