August, welcome, you might need to start a new thread for this to get good answers...the scores you describe sound pretty rare to me, might be more of a 'how many in 10,000' thing. But I am not really that in the know to confirm this.
I will say there is a thread around here about shockingly-low coding scores and whether that correlates to a 'type' of kid or learner (my son has a pretty low coding score). I'll see if I can dig it up.
