integer and string compare, is that correct?

If you actually need to perform comparisons across types, you can rely
upon the fact that tuple comparisons are non-strict and use e.g.:

	> a = 5
	> b = '5'
	> (type(a).__name__, a) < (type(b).__name__, b)
	True
	> (type(a).__name__, a) > (type(b).__name__, b)
	False

The second elements will only be compared if the first elements are equal
(i.e. the values have the same type).
