You can try this:

select = new OpenLayers.Control.SelectFeature(vectorLayer, {
    callbacks: {
        click: functionC,
        over: functionH,
        out: functionO
    }
});

By doing so note that:

 * you're going beyond the SelectFeature API, in other words things
could change from under your feet and your code could eventually fail

 * the provided callbacks override the default callbacks defined in
the select feature control, meaning you're totally on your own. For
example, no styling will be applied to the selected features.

There seems to be an order issue. Try to activate "hover" first and then click.

Hope this helps,
