Ordering Movieclips with AS3

Hi everyone.

I’ve implemented a ‘bitmap overlay’ (just what I’m calling it) using the following code:

var bmpd:BitmapData = new BitmapData(2, 2, true, 0);
bmpd.setPixel32(0, 1, 0xff000000);
bmpd.setPixel32(1, 0, 0xff000000);

Along with other bits and pieces.
Basically, a group of pixels cover the entire stage.

However, I need some movieclips on my stage (text, like titles etc) to be on top of the bitmap overlay.

Is there some way I can order the movieclip on the stage to be on top of anything else produced using pure actionscript?

Thanks for any help you can provide in advance.
