Actually it returns None, as you'd see if you
print __builtins__.__dict__.keys().sort()
which is what sort() always returns.

Another good occasion to read the documentation:
"The sort() and reverse() methods modify the list in place for economy of 
space when sorting or reversing a large list. To remind you that they 
operate by side effect, they don't return the sorted or reversed list."

So try:
keylist = __builtins__.__dict__.keys()
keylist.sort()
print leylist
