I work regularly with autistic children. Autism isn't just associated with social anxiety, it's usually social impairment and a complete inability to understand and adapt to social norms. Importantly, it occurs right from early development. The other stuff you mentioned, is, as other mentioned, more characteristic of ADD, which is often comorbid with autism, but not autism itself.
Also, actual autism is very rare in girls, only occurring in around 1 in 189 of them, vs. 1 in 42 for boys, so the odds of her having it are just low in general
