I think that's expected behaviour.  Note that int vs float behaves in the same way as float vs complex:

>>> class xint(int):
...     def __radd__(self, other):
...         print "__radd__"
...         return 42
... 
>>> 3 + xint(5)
__radd__
42
>>> 3.0 + xint(5)  # xint.__radd__ not called.
8.0

As with your example, the float.__add__ method is happy to deal with an int or an instance of any subclass of int.
