Is your suggestion something like this?

  def __cmp__(self, other):
      return cmp(intrev(self), intrev(other))

or

  def __cmp__(self, other):
      if self == other:
          return 0
      elif other in self.ancestors():  # naive implementation
          return -1
      else:
          return 1

I agree it will be sometimes convenient, but I'm not sure how often we'll
do "ctxa < ctxb".
