в вашем коде много непонятного, но может вот так?

var ml:MovieClipLoader = new MovieClipLoader();
var ls:Object = new Object();
obj_mc = this.createEmptyMovieClip("obj_mc", 1);
for (var i:Number = 1; i<9; i++) {
	obj_mc.createEmptyMovieClip("foto"+i, i);
	ml.loadClip(_global[i+"opt"], obj_mc["foto"+i]);
}
ml.addListener(ls);
ls.onLoadInit = function(mc:MovieClip) {
	var x:Number = mc._x;
	var y:Number = mc._y;
	mc._x = (i*60)-10;
	mc._y = 5;
	mc._xscale = 15;
	mc._yscale = 15;
	mc.onRollOver = function() {
		mc._xscale = 30;
		mc._yscale = 30;
	};
	mc.onRollOut = function() {
		mc._xscale = 15;
		mc._yscale = 15;

	};
	ml.addListener(ls);
};
