More gems:
>>> Decimal(3) < 4.0
False
>>> Decimal(3) == 3.0
False
>>> Decimal(3) > 4.0
True

And the pièce de résistance:
>>> l = [2.0, Decimal(3), 3.5, Decimal(4), 5, 3]
>>> for i in range(5): random.shuffle(l); print sorted(l)
[2.0, Decimal("3"), 3, 3.5, Decimal("4"), 5]
[2.0, 3.5, Decimal("3"), 3, Decimal("4"), 5]
[2.0, Decimal("3"), 3, 3.5, Decimal("4"), 5]
[2.0, 3.5, Decimal("3"), 3, Decimal("4"), 5]
[2.0, 3, 3.5, Decimal("3"), Decimal("4"), 5]

(The positions of 3 and Decimal("3") should be swapping, but the
position of 3.5 should not.)
