You should look into the core classes to see what goes on behind the scenes:

mx.core.UIComponent
mx.core.UIObject

UIObject uses 2 private variables to keep track of width and height

 var __width:Number;
 var __height:Number;

In your size() method use those instead of the default _width and _height 
(movieclip) properties.
