I would think that, on the whole, a higher GPA is better than higher test scores. The first measures performance over years, the other over a few hours. Tippy tops and T20 schools are in a league of their own, though. Without a hook or significant achievement, excellent GPA and test scores are a baseline, not a tip.
OP, while your GPA is a smidge low, you’re close enough to be considered a serious candidate.
They’re building a class, not just racking and stacking. Once you meet their baselines that prove you can do college work, what’s twenty or thirty points on a high school test score (that will mean nothing to anyone a year from now) if X candidate plays the sport in which they are most in need of recruits (or is a champion debator and may join the college team, which has been looking weak the past couple of years and needs a few strong participants), and what’s a 3.8 vs. 4.0 GPA if the 3.8 is a viruoso in a desperately needed instrument for the marching band or orchestra?
