integer and string compare, is that correct?

The use cases for an order that works across types like int and str are weak 
to non-existent. Implementing it was considered a mistake and has been fixed 
in Python 3:

Python 3.1.1+ (r311:74480, Nov  2 2009, 15:45:00)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 5 > "5"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unorderable types: int() > str()

Checking for equality is still possible:

>>> 5 == "5"
False
