Keyframes work great for that. If you want to use a behavior to make an object Scale down and then come to a nice gentle halt, the one you are after is the “Move” behavior. Change it’s Z position (in 2D) and it will give the appearance of scaling up or down. When you want it to stop end the length of the behavior.
Check out the ring logo animation example in this commercial, this is taught in chapter 3.2 of my Moving with Motion training DVD, everything is being animated by a behavior in the video. Notice how the brown ring comes to a nice gentle stop once it scales down.
Hope this helps and best of luck.
