Jonathan Levi made it 1-0 to Elfsborg away team after a quarter when Yaser Kasim accounted for a horrible pass.
Half an hour later, however, Örebro acknowledged. The ball took on Sivert Heltne Nilsen's arm and Jake Larsson put the receipt from the penalty spot.
At the beginning of the second half, it was Elfsborg's turn to get a penalty at hand, but that time Jansson was included in the score.
With just under ten minutes left, it happened again. That time, 18-year-old Helmer Andersson took the ball and the skipper Stefan Ishizaki managed it safely.
But Örebro managed to acknowledge again. In extra time it was sloppy in Elfsborg's penalty area and the ball landed with Johan Bertilsson who thundered in the receipt.
With two games left to play, Elfsborg is four points ahead of Örebro. Örebro will also meet the top teams Djurgården and Malmö who are currently settling for the SM gold together with Hammarby and AIK.
