The Skeleton Horse when out in the sun without armor does not burn.
Since it is an undead mob, and the Zombie Horse burns in sunlight, it is uncharacteristic of it to not burn in the sun.
It should burn in the sun like every other non-special undead mob.

Well, it was a bug (MC-302656 ), since skeleton traps activate during daytime too and skeleton horses don't have the slot for the horse armor, it wouldn't be convenient to make skeleton horses burn the sunlight.
