To say something is unverifiable isn't to say that all possible attempts to prove it would fail. It's to say there are no well-defined observation conditions for its truth, and therefore that the idea of an attempt to prove it true is meaningless. As you know from reading Ayer.
Obviously it's a bit of a buncombe notion, which is why you have to have falsifiability as well.
