The Kangaroos came from behind to pinch the third NAB Cup game at Etihad Stadium, with young forward Aaron Black kicking the sealer with 40 seconds left.
"Winning becomes a habit for good teams and those that find a way to win," Scott said.

"I think back to the Geelong game last week … they find a way to win, those guys, they've done it for so long.
"For us, we're trying to develop that winning feeling and regardless of what people say about the competition - I think it's in great shape.
"Melbourne and Richmond certainly played their best available squads and we did too so I thought the quality of footy was pretty good tonight."
Scott said the fact both games were won by less than a goal, with young players Majak Daw, Daniel Currie, Will Sierakowski and Jordan Gysberts impressing at times, made the results worth even more.
"You want to expose your players to that winning feeling in tight games as often as you can," he said.
"There are certain things you want to be able to do when the game is tight, whether you're a little bit down or up.
"You can practice that at training all you like but until you've got some genuine pressure you don't know how you're going to go, so it's always good to come out the right side."
