You can actually accomplish this by finding these three lines in the javascript
and changing them as shown:

Spry.Widget.Accordion.addEventListener(tab, "mouseover", function(e) { return
self.onPanelTabClick(e, panel); }, false);

Spry.Widget.Accordion.addEventListener(tab, "click", function(e) { return
self.onPanelTabMouseOver(e, panel); }, false);

Spry.Widget.Accordion.addEventListener(tab, "mouseout", function(e) { return
self.onPanelTabMouseOut(e, panel); }, false);
}
