You can setSortMode() on the RenderBins that you're using.
RenderBin* rb = RenderBin::getRenderBinPrototype("RenderBin");
rb->setSortMode(SORT_FRONT_TO_BACK);
In the code above, "RenderBin" == the opaque bin. You probably don't want to
change the sorting method used by the transparent bin (but if you do, it's
name is "DepthSortedBin" -- it sorts back to front by default).
In the past, I've had to create my own sorting method. To implement this, I
created my own custom RenderBin and overrode sortImplementation(). This is
really overkill for what you're doing.
Hope that helps,
