The Iron dominated possession throughout but had to wait until the 68th minute before midfielder Mark Duffy broke the deadlock.
"We looked solid enough at the back but I have to confess we looked a bit toothless in attack in the second half," Smith said.
"Scunthorpe were the better team in the second half of what was a tight game between two teams battling for points.
"They also created the better chances but I thought we had weathered the storm when they scored.
"And I feel we did enough in the game to have come away with something."
