Lee Bell gave the visitors a 34th-minute lead with his fourth goal of the season and first for five games. But man-of-the-match Scott, back at Victoria Road after a loan spell at Ebbsfleet, equalised in the 51st minute with his second goal in as many games to secure a point.
"It wasn't the one player who made the difference, but all credit to Josh because he took his goal really well," praised Hackett.
"The situation with Josh is that he went out on loan - and maybe it was the kick up the backside he needed.
"He's come back, got the bit between his teeth and wants to prove a point to everybody that he is a good player.
"Josh is a good player. He got a goal on Tuesday, it lifted his confidence and he's got another goal. Onwards and upwards for Josh."
Brewers boss Gary Rowett was left frustrated after his side failed to increase the pressure at the top of the table.
"I thought we played really well in the first half, we were the better team," he reflected. "But we conceded a bad goal and that gave Dagenham a lift.
"We always knew it was going to be tough coming here but we didn't really kick on in the second half and get that second goal we were looking for.
"It's a shame we've slipped a place in the table but there's still a hell of a lot to play for and a lot of games left. We've just got to keep going, keep working hard and keep doing what we've done so far this season to get us into this great position."
