Gordon Strachan's men have only won once in qualification so far, a 1-0 victory against Croatia in June, but maximum points from the remaining two games could yet mean a third-place finish.
Scotland are currently bottom of Group A, after a 2-0 loss to leaders Belgium on Friday night coming after they had already been ruled out of a place in Brazil, but Griffifths wants a late revival starting with Macedonia on Tuesday.

"We have only got two games left so hopefully we can get six points from them. We knew it would be a difficult game on Friday and we know it will be the same on Tuesday as well."
The former Hibernian striker made his fourth appearance for his national side from the bench on Friday after scoring four times in five games for League One side Wolves this season and hopes that his fine form will see him given more game time in Scotland's final matches.
"I'm hoping to get game time but that's up to the manager to decide if he wants to start with me or put me on the bench and I can have an impact from the bench," he added, "but, whatever team he puts out I'm sure we will do well."
