According to the wpa_supplicant AP scoring, it would indeed seem that the 2.4GHz AP is proffered since it has better SNR (although the SNR for both is good. Generally, wpa_s considers any SNR above 30 as good).

a0:55:4f:66:d5:18 freq=2447 qual=0 noise=-89~ level=-49 snr=40* flags=0xb age=0 est=65000
a0:55:4f:66:d5:10 freq=5240 qual=0 noise=-92~ level=-67 snr=25 flags=0xb age=0 est=390001

perhaps the scoring can be tweaked to more aggressively favor 5.2 in case of close good SNR.
