Please do make inquiries, as I would be very interested in hearing what they have to say. As for my conviction, when I inquired as to the reason I was not qualified, the official answer was I did not have an ICAO license. The information about South Africans and Americans admittedly came from two other people in the company that should have knowledge, one moreso than the other.
As for Bahrain, if I am not mistaken (and I certainly could be) they have an ICAO license once they are validated, so an American could certainly qualify for the job at Doha in that regard. To that end, I would be qualified once validated here, as I too would then have an ICAO license.
I do agree completely on making sure what you need or expect is written into any offer before you sign it! Verbal agreements are worth as much as the paper they are printed on...
Enjoy your evening!
