Lewis Grabban's double, the second from the penalty spot, and a wonder goal from sub Brett Williams meant the Millers kept in touch with the play-off runners, leaving Scott happy with an improved display after the break.
He told the press afterwards: "The first half was very poor, we didn't have the energy that we normally have, it looked a little lacklustre as if we were waiting for something to happen,
"I was going to make a change at half-time but then Danny Harrison wasn't well at all so it was an enforced change, with Jon Harley coming on and Sam (Wood) going to wide left and Schoey going into the middle.
"In the second half we looked a totally different side, we controlled the game, passed it well and got crosses into the box. We created chances, counter attacked when needed and defended really well, everyone in the first half was frustrated but the second half was much better and we completely controlled the game."
Scott added: "The work that Alex Revell did was outstanding. He was up against two big powerful centre halves but he causes problems. When we are in trouble he is a good outlet for us and his work rate is phenomenal. The work that he does can be underestimated, he allows players like Lewis Grabban to get involved from wide areas, and he gives us an outlet that we didn't have before he came."
Meanwhile Harrison was taken to hospital for a check after suffering bleeding from his ear, but is expected to be fine.
