Python 2.4 gives the same behavior on Windows:

ActivePython 2.4.3 Build 12 (ActiveState Software Inc.) based on
Python 2.4.3 (#69, Apr 11 2006, 15:32:42) [MSC v.1310 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from pickle import dumps
>>> from cPickle import dumps as cdumps
>>> print dumps('1001799') == dumps(str(1001799))
True
>>> print cdumps('1001799') == cdumps(str(1001799))
False
>>> print cdumps('1001799')
S'1001799'
p1
.
>>> print cdumps(str(1001799))
S'1001799'
.
>>> print dumps('1001799')
S'1001799'
p0
.
>>> print dumps(str(1001799))
S'1001799'
p0
.

This does seem odd, at the very least.
