Tween Max AS3 Not Working on Root of loaded SWF

Question

     I have a project where I'm loading a SWF into another Shell SWF and I've run into a strange bug.  Tween Max works in the compiled clip everywhere, but on the root of the loaded SWF.  It's not erroring out, it's just not tweening anything?
Here's the code for the loader in the Shell...
stop();
//Import the required assets
import flash.display.*;
//Stop the playhead while loading occurs
var ldr:Loader = new Loader();
var url:String = "12com2682-value.swf";
var urlReq:URLRequest = new URLRequest(url);
ldr.load(urlReq);
//Create a listener to call the loading function as the movie loads
ldr.contentLoaderInfo.addEventListener (ProgressEvent.PROGRESS, PL_LOADING2);
function PL_LOADING2(event:ProgressEvent):void {
loader_txt.visible = true;
var pcent:Number=event.bytesLoaded/event.bytesTotal*100;
//Display the % loaded in textfield
loader_txt.text="loading:"+int(pcent)+"%";
//If the movie is fully loaded, kick to the next frame on the main timeline
//You may wish to change the gotoAndStop(2) to a gotoAndPlay(2)
if(pcent==100){
          mc_loadscene.addChild(ldr);
          loader_txt.visible = false;
this.loaderInfo.removeEventListener (ProgressEvent.PROGRESS, PL_LOADING);
then in the loaded SWF, I have:
stop();
import com.greensock.TweenMax;
import com.greensock.plugins.*;
TweenPlugin.activate([AutoAlphaPlugin]);
import fl.transitions.easing.*;
//////mc_host is a movieclip holding a video
TweenMax.to(mc_host, 1, {scaleY:1, scaleX:1, delay: 2.5, ease:Back.easeOut });
//////mc_sidert is another movieclip
TweenMax.from(mc_sidert, 2, {y:"-600"});
Anybody else running into this error?

you must be doing something wrong because that code works as expected for me:  http://www.kglad.com/Files/forums/test2.html and http://www.kglad.com/Files/forums/test2.fla
