It would be an interesting two-step test... do it first just as the meta keyword, then, if there are no results, hit it with inbound link(s)

Robert - one IBL by itself might be enough for a page to rank, even for a gibberish phrase - at least this was the case when I tested a few years back. So I'd suggest a 'control' page that is linked to from the outset with the same phrase.

If that is found from the start then it makes the job of proving that it's the COMBINATION of keywords tag and IBL that's producing results far harder to do, if just a link on its own will suffice.
