Soup,
That sounds like our school. It's rubbish, just delay tactics.
They are trying to wear you down. Don't let them win!
When I asked that my son be tested for Gifted, I was told that he needed to wait another year and take the SAT10 again. They had mistakenly written that he scored in the 98th PR and they wanted to give him a chance to do better. Luckily his score was actually in the 99th PR and you can't really do better than that so that was the end of their argument. But they did argue.
I don't believe the GT coordinator is being helpful. Why don't you write a letter (attach documentation) to the superintendent and copy the School Board. If this is your last shot, go out in a blaze of glory.
