With your above example, your zoom level when you call map.getZoom() will be something between 0 and 5. This is because map.zoomTo() is asynchronous now, at least when a zoomMethod is configured for the map.
So instead of calling getZoom() directly, you should register for a zoomend listener and call getZoom() there. Andreas.
