Based on what you wrote, I don't think that there is any question that she is going to need serious accommodations in school. She clearly is. As far as the test is concerned, I would look at it as evidence that she is gifted, but not evidence of how gifted. Even if she is only MG (which doesn't sound like it is the case), she is not going to do well in a regular classroom.
I think now is a great time to think about your options. If she goes to K on time, will your school consider a grade skip a few weeks into school? Will they make significant accommodations within the K classroom? Is homeschooling an option? Are there gifted schools in your area that might provide more challenge?
