Welcome!
None of his scores are by any means weak. Some are just stronger than others. Given his language environment and his age, it would not be too surprising if the verbal area were higher in future years. I wouldn't be concerned about this, as, long term, it will be greatly to his benefit to be multilingual.
The relative weakness in working memory refers not to long-term retrieval, which is the IRL strength you describe, but to short-term memory skills. It's more like how many instructions he can hold in his head at once. Often, it is actually related to sustained attention. Or it can be the other way around--that he appears to be inattentive because of the challenge of holding multiple things in his head. It's also often the case that attentional issues have more impact on social skills, for several reasons, including impulse control. Also, most social skills are learned from experience, which requires sustaining attention all the way through from behavioral cause to social effect.
On the other hand, instructional mismatch (insufficient academic challenge) can also produce behaviors that appear to be inattentive and impulsive, because the child is seeking stimulation for a different reason. These can have the same kinds of impact on social interactions. In addition, the absence of cognitive peers may feed into social disconnection for some high-cognitive children (not all--some children are particularly skilled at reading the room, and make adjustments to their own presentation in order to either mask/"fit in", or actually find a way to connect with diverse peers).
His learning profile would suggest that he might find mathematical and spatial puzzles appealing, which is one area you could investigate outside of school. If he likes math, there are also a number of in-person and online math enrichment resources you may find on the Recommended Resources page of this forum, giving the preference to conceptual and creative math, rather than procedural drills (unless he enjoys those).
Did the school do any other testing, such as academic achievement? That might give us some additional directions to suggest.
