"...but international jet aircraft have priority over domestic jet aircraft"
Don't think so.
Besides some management and economic benefit reasons that may be applied,(and your AIP List) I think you will find that it is first in, first served, with scheduled commercial air transport and non-scheduled air transport having priority over general aviation.
Beer Barons post makes more sense.
"Jet aircraft also tend to have lower minima than turboprops."
Bit of a generalization there!!
