MaskedArray ignores __array_priority__ #5227

Given a class like this:

class X(int):
    def __add__(self, other):
        return 42
    def __radd__(self, other):
        return 24
    __array_priority__ = 20

Adding to a numpy array works as expected:

>>> np.array(2) + X()
24

However, when I add X() to a masked array, X.__radd__ is not called:

>>> np.ma.array(2) + X()
2

This seems resolved in current master (with #5964 merged). @abalkin - can this be closed?
