But the winless streak for cross-district side ECU Joondalup stretched to 11 games when the Jacks drew with Perth Glory 2-2.
Sorrento�s win sets up an intriguing clash against third-place Perth away this weekend, with the fourth-placed Gulls able to snatch the superior position with victory.
In last weekend�s match at Percy Doyle Reserve, Todd Harnwell opened scoring in the first half before teammates Jack Eades and Ryan Pearson made it three goals in the second.
Assistant coach Steve Neville told nplwa.com.au the side had been trying some different formations in preparation for its FFA Cup clash against the A-League�s Sydney FC next week.
�It took us a little while to get used to the system,� he said.
�At the moment we are in a winning habit and we want to keep that going to the end of the season.�
At Inglewood Stadium, the injury-ravaged Jacks made a comeback from 2-0 down late in the game to salvage a draw against the Glory youth.
Perth scored its second goal in the 66th minute, but 13 minutes later, ECU sub Paddy Doyle landed his side�s first before Tommy Amphlett hit the equaliser in the 85th minute.
ECU is just one point ahead of last-placed Glory, having lost nine of its past 11 games.
The Jacks face Floreat Athena at home on Saturday.
