Jermaine Easter grabbed his ninth goal of the season just after the half-hour mark to see off Walsall and lift in-form Milton Keynes up to fourth in the table.
And Ince - who lost defenders Dean Lewington and David McCracken to injury against the Saddlers - believes his patched-up Dons will be a real threat to the top two once their lengthy injury list eases.
He said: "We didn't play like the MK I know but when you look at the circumstances of the game, losing our centre-half and then our captain, it was a good win.
"When I look at the top two they seem to be able to pick their first 11 every week - I haven't had that luxury so far. When we get our injured players back and I've got 24 players to choose from we'll be able to see what we can really do.
"I'm pleased with the start we've made but I'm not getting carried away."
