На сайте adobe во "Flex SDK coding conventions and best practices" пару слов на эту тему:

If a class overrides a getter/setter and wants to continue to expose the base getter/setter, it should do so by implementing a property whose name is the base name with a $ prepended. This getter/setter should be marked final and should do nothing more than call the supergetter/setter.

mx_internal final function get $numChildren():int
{
    return super.numChildren;
}
