Exactly their recent games especially their strong win against Namibia show they are confident team with momentum. You are right to point out Scotland batting. Fact is that they were able to chase 185 runs and only lose three wickets against Canada was showing their great strength and depth. So it means they can handle both setting and chasing high scores. Inconsistency you mentioned in Canadian team is key point. They scored decent total but their bowling and overall performance were not good enough to beat Scotland. It looks that Scotland consistency and strong batting make them team to beat in this match.
