The testcases notwithstanding, I found a bug in my code as well. Fixed my `response` function to:

    def response(h, g):
        assert len(h) == len(g)
        L = len(h)
        correct = [i for i in range(L) if h[i] == g[i]]
        present_h = []
        present_g = []
        for i in range(L):
            # We want to check whether g[i] is "present" in h
            if i in correct: continue
            for j in range(L):
                if j in correct: continue
                if j in present_h: continue
                if h[j] == g[i]:
                    present_g.append(i)
                    present_h.append(j)
                    break
        return (correct, present_g)

and now I too get (AESIR, ARISE, RAISE, REAIS, SERAI) all leaving 168 words. (But the testcases in the above comment still hold, though, make sure your code works for them.)
