This was fixed. The current code has:
convert = {
'__lt__': [('__gt__', lambda self, other: not (self < other or self ==
other)),
('__le__', lambda self, other: self < other or self ==
other),
('__ge__', lambda self, other: not self < other)],
'__le__': [('__ge__', lambda self, other: not self <= other or self ==
other),
('__lt__', lambda self, other: self <= other and not self ==
other),
('__gt__', lambda self, other: not self <= other)],
'__gt__': [('__lt__', lambda self, other: not (self > other or self ==
other)),
('__ge__', lambda self, other: self > other or self ==
other),
('__le__', lambda self, other: not self > other)],
'__ge__': [('__le__', lambda self, other: (not self >= other) or self
== other),
('__gt__', lambda self, other: self >= other and not self ==
other),
('__lt__', lambda self, other: not self >= other)]
}

To avoid needless posts, you should use the tracker.
