You do not use CSS z-index here. All you have to do is set the
graphicZIndex property of your symbolizer, as the ordering.html example
shows:

var layer = new OpenLayers.Layer.Vector(
    "Y-Order",
    {
        styleMap: new OpenLayers.StyleMap({
            externalGraphic: "../img/marker-gold.png",
            pointRadius: 10,
            graphicZIndex: GOLD_Z_INDEX
        }),
        isBaseLayer: true,
        rendererOptions: {yOrdering: true}
    }
);

You will not want the yOrdering renderer option, but instead:

        rendererOptions: {zIndexing: true}

Andreas.
