making a GUI.Label displayed behind spawned gameobject

hi everybody.

i've created a GUI.Label for my 2d game that shows the score. in my game there are spawned gameobject that fall down in the scene from the top of the screen.

i've placed my GUI.Label in the upper center of the screen. the problem is that my spawned object are displayed behind the GUI.Label: they are covered by the score.

is there any solution to make the Label diplayed behind the spawned object?

i instantiate my object giving a position like

     Vector3 pos8 = new Vector3 (xValue, yValue, 0);

so they're created at a z=0 position.

the z position of the GameObject on which is attached the script that creates the GUI.Label is set at 10 but the score is still in foreground.

i've also tried to assign a positive depth to my label in this way:

 void OnGUI(){
         GUI.depth = 10;
         GUI.Label (rett, " " + playerScore , style);
     }

but is still not working.

thanks for any help!
