The outdated stuff on Scorpion's profile is pretty much the hellfire burning souls and all the powers he gets from the Netherrealm.
Still, this is human Scorpion and it isn't very in-character for him to BFR people, that belongs more to his undead persona.
About the match itself, I also see Scorpion winning. This version of him has decades of experience and training, he is a seasoned grandmaster who holds great control of his abilities and went through dozens of battles against a variety of opponents, with many of them outright trying to murder him.
This Zoro is a very capable swordfighter, but is still quite inexperienced. His biggest advantage are his Lifting Strength, longer reach with swords in close combat and an unusual style, as anime swordsmen like Zoro fight in a unique way.
Three swords are also a new thing, but Scorpion has faced several dual wielders, enemies with multiple limbs and ever more than one opponent at the same time, on top of being a dual wielder himself.
Scorpion also has a variety of ranged options and tricks, he can employ his fire in many ways and it obviously burns, can teleport, summon minions, spawn fire below Zoro, become intangible and more. The clouds of mist that could be formed are also an advantage to Scorpion with his stealth skill.
Finally, if Scorpion manages to disarm Zoro in some way, he just overwhelms him in martial arts.
