The algorithm is probably described somewhere in the documentation
but my understanding is that it looks something like this(in pdeudo code):

def isEqual(X,Y):

    if len(X) != len(Y): return False

    if X[0] != Y[0]: return False

    return X[1:] == Y[1:]


def isGreater(X,Y):

   if len(X) <= len(Y) return False

   if X[0] < Y[0] return False

   if X[0] == Y[0] return X[1:] > Y[1:]

   return True


And similarly for the other operators.

But that's just based on playing with the interpreter and exploring
different values...
