Welcome!
Whether you find the scores "sufficient" depends a lot on the purpose of testing. My usual suggestion is to test only if there is a specific reason:
1. The scores are needed to access a service which you believe is essential for your child (e.g., a school, program, or other resource).
2. There is a problem which needs disentangling, and having a clearer idea of the learner's cognitive profile would help to identify that problem and the appropriate solution strategies.
In your case, there does not appear to be a resource that fits #1, but you may have a question that fits #2. You also have an hypothesis about the answer to that question, but limited data either to support or to contradict the hypothesis. If the social and personality overexcitabilities you contemplate are not significantly impairing his general development, health and happiness, then testing might not be helpful, as it likely would not add information to your understanding of him. If you have reason to believe they are impairing his access to major life functions, then it might make more sense to pursue an evaluation with a broader scope, as giftedness is not the only possible explanation for these categories of concern. It's better to go into evaluations with an open mind about the range of possible outcomes (in various domains of development, not only intellectual).
