Question on Palo Alto QOS tags

tl;dr - Isn't higher number = more priority with Layer 2/CoS QoS? Or is Palo Alto different?

I inherited a Palo Alto setup from the prior guy who inherited it from the prior guy who was (supposedly) a firewall expert. I noticed something weird with regards to the QoS config, and I'm wondering if I'm wrong or if maybe this guy wasn't the expert that I'm told he was.

Screenshot!

This is a flat L2 network, no routing anywhere, so I understand that CoS tags are appropriate. But . . . in CoS, isn't higher number = better? I thought the standard for 802.1p was 5 for Voice and 4 for Video.

Does Palo Alto do L2 QoS tagging differently, or did "that guy" have his wires crossed?
