The GraphicsLayer watches for changes to its graphicsProvider.

See:
http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/layers/GraphicsLayer.html#graphicProvider

Try:

public function moveGraphicToBack(graphic:Graphic):void
{
    var graphicsProvider:ArrayCollection = graphicsLayer.graphicProvider as ArrayCollection;
    
    var index:int = graphicsProvider.getItemIndex(graphic);
    if (index > -1)
    {
        graphicsProvider.removeItemAt(index);
    }
    
    graphicsProvider.addItemAt(graphic, 0);
}
