Generate parsing rules for ML tactics in the same order as before a7917a32.
Generate parsing rules for ML tactics in the same order as before a7917a32.

Once again showing the fragility of the parsing engine, commit a7917a32

declared through TACTIC EXTEND. There is probably no good order at all, but
for retrocompatibility, this patch enforces the original one.
