The Millers came through a testing second half to hold on to a 2-1 scoreline and remain top of the table.
And Scott praised his players, telling Radio Sheffield that his team have the qualities to grind out a result.
"Sometimes in this league you've got to come away from home and you've got to graft and be solid, organised and prepared to put your body on the line and not play great but get a result," he said.
"sometimes if you're not playing great, things go against you, if you buckle it shows a sign of weakness. We haven't got that, we're organised, we're strong and we're prepared to battle for eachother and they enjoy doing that.
"I'm proud of every one of the team, its been a tough start to the season, everyone thought it would be and sometimes these scruffy wins are good."
