I might be misinterpreting the evidence, but sorting works on objects
that define `__gt__` without `__lt__`.
py> class A:
... def __init__(self, x): self.x = x
... def __gt__(self, other): return self.x > other.x
...
py> L = [A(9), A(1), A(8)]
py> L.sort()
py> [obj.x for obj in L]
[1, 8, 9]
This class supports '<':
>>> A(1) < A(2)
True
The `<` operator try to use `__lt__`, but if it is not defined falls
back to `__gt__`.
