The only negative however was a hand injury suffered in the last play of the game, which almost certainly rules him out of Sunday's meeting with South Africa.
Scott has struggled with niggles already this campaign, injuries have restricted him to only two RaboDirect PRO12 appearances this season.
But while disappointed to be without the centre's services next weekend, Johnson tipped his man to make an impact in the long term.
"It is well documented what I think the kid can be," Johnson told The Scotsman. "He is not there yet but he is going to be a special player.
"He is a special kid and a special player, and I think he can go further in the game than we are willing to admit.
"He is a wonderful athlete with good skills and good feet - that's a lot of boxes ticked there. I am glad he is playing for us. I will be incredibly glad in a couple of years' time because I think the world will be talking about him.
"Disappointingly, he has been banged up on the last play there and it was the one thing we wanted to get him through to the end, but it opens the door for somebody else probably."
