Billy Kee gave the hosts the lead only for Deon Burton and Niall Canavan to put the Iron in front with quickfire goals after the break.
But Robbie Weir headed the Brewers level in the 62nd minute as they picked up a welcome point.
Kee went close to celebrating his return from a six-week injury lay-off with a fifth minute goal, but was denied from eight yards by Sam Slocombe's instinctive save.
Burton's pressure paid off when Kee arrived at the far post to hammer Alex MacDonald's driven cross into the roof of the net in the 37th minute.
The visitors made amends for a lacklustre first half show with two headed goals in four minutes after the break.
Burton levelled the scores when he glanced in a Terry Hawksworth cross in the 48th minute and then Niall Canavan struck from close range after running onto Andy Dawson's corner.
The Iron were guilty of equally poor marking when Weir found the space to beat Slocombe with a stooping header from Chris Hussey's free-kick.
