I updated [1] the StyleMap example [2] to demonstrate how to use z-indexing with different render intents. In addition to using a graphicZIndex (will eventually be zIndex) property in your symbolizers, you need to enable z-indexing on the renderer. To do this, set rendererOptions on your layer as shown in the example. To see z-indexing with selection in action, refresh the example until you see overlapping points. When you hover over a point, the render intent changes to "select" and you should see the selected feature drawn over others.
