Schlierenzauer claimed his second overall ski jumping World Cup title with a fifth-place finish in Kuopio on Tuesdeay, having won the crown for the first time two years ago.
However he went into the third from last World Cup event of the season in Oslo having not won in five and only finished in the top three twice during that time.
But Schlierenzauer was back to his best in Norway as he produced the biggest jump of round two to move up from fourth after round one and take the joint victory with Zyla.
Schlierenzauer, who leapt 134.5m for 133.1 points in round one, recorded a distance of 135m for 137 points second time out and an overall total of 270.1.
Zyla placed third after round one with his leap of 135.5m giving him 137.1 points before an effort of 133.5m for 133.0 points meant he claimed his debut win tied with Schlierenzauer.
Robert Kranjec was the leader after round one with an effort of 134m producing a score of 141.6 points however he was the ninth best during round two to fall to third.
Kranjec's jump of 126m gave him 125.2 points and 266.8 overall with Stoch placing fourth with 260.0, Anders Jacobsen fifth with 259.0 and Wolfgang Loitzl sixth with 254.1.
The World Cup now moves to Planica for the final two individual events of the season as well as the team finale all of which are ski flying competitions as opposed to ski jumping.
