The first argument for `push` is the element, the second argument is
the place you want to put it. I think you have the order wrong, and it
should be

    (push (match-string 0) commands)

Also worth noting: OP has written self-modifying code, by let-binding
empty lists which will get mutated.

And that `(if (not` should be an `(unless`.
