County led at half-time at Meadow Lane following a terrific goal by skipper Neal Bishop after Orient had seen the better of the chances.
However, the visitors levelled midway through the second period when County defender Dean Leacock gave away a penalty with a rash challenge on Charlie MacDonald and substitute Kevin Lisbie converted the spot-kick with confidence to seal a point.
Kiwomya said the point was not enough at this stage of the season if the Magpies are going to push for a top-six place.
He said: "If we want to get to the play-offs these are the kind of games we need to win.
"We were disappointing first half. We defended too deep and let them have the ball and they began to dictate play. Neal's goal was the first time we had got into their final third and played a forward pass.
"We pressed them a bit higher in the second half and I think we had the better chances.
"I haven't seen it back but I've no complaints about the penalty. It gave them a foothold in the game.
"I know what we are lacking and I know what we need and I need to find that right player to get us some goals."
