question about discrepancy between verbal and performance IQ

It suggests nonverbal weaknesses relative to verbal but alone does not indicate LD. The bigger question is probably what is the range of scores. My son has a similar spread to yours but clearly has some nonverbal issues. He scored 5 and 6 on two performance measures and 13 on other measures (both performance and verbal). This “all over the place” is typical of kids with LD.

Why were you having your child tested? LD can not be determined only from IQ scores.

I’m not a test specialist, but as a teacher honestly I would consider these normal scores. Both are very close to the average of 100, and if you re-tested, day-to-day variation could make one higher and the other lower by as much as five to ten ponts.

The “magic number” varies with legal definitions from state to state but if a discrepancy model is being used you need a difference of over one or two standard deviations, fifteen to thirty points. And you are looking for one of the scores to be in a different range from the other, say one in gifted and the other in low normal, where in fact what you have is both solidly in the middle of average.

If you are really concerned about your child’s abilities you can have retests done with other tests. This would be appropriate if something is very off in the child’s school or social or speech achievement.

But seriously at this point I would usually recommend good academic tutoring with proven effective reading and math strategies. If these IQ scores are a good indication of the chld’s abilities, there should be no problem once initial difficulties are overcome.
