Sturrock said: "Rory scored an identical goal to the one he got at Peterborough again today.
"He is a threat in the air when he is playing like that and he is also good in defence with his aerial ability.
"I think the win in the week has buoyed the boys. Before if they had got pegged back they would have let it affect them.
"Today they have gone straight up the other end and got a goal back, which turned out to be the winner."
Disappointed Iron boss Nigel Adkins said: "We came here with a game plan to play narrow, through the middle and get the Hayes-Hooper combination going against their young centre-backs and it's worked well.
"The first half I was pleased with but we had good opportunities and have not taken them.
"We have come away from home and we are looking nice and solid and could have scored three or four goals in the first half.
"We had talked about the threat of Fallon, just an easy ball into the box and if you don't stop the cross or don't compete you give him an opportunity.
"We targeted this game as one where we could take all three points because Plymouth are struggling and we have come away with nothing."
