Counter brick sounds like what you need. With every loop of the animation you trigger the Counter brick to count up. Once the Counter reaches its Count, have it trigger your value increase thing.
Edit: If "value increase" means you want to increase multiple times, not just set a different value...that is also possible. Use a second Counter that is triggered from the first one. For an example, check the Counter example that comes with the LogicBricks Demo scenes. There is a Counter brick used to drive a Slider value.
