Jquery Tabs

Hi,
I would like to change my old TwentyTen theme for a more mobile friendly one. Your theme seems would be just fine for me. The only problem I use lots of Jquery Tabs and I can’t make them working with your theme. I wonder if you could help me figure out what the problem is. I try to change header.php adding the following code:

wp_enqueue_script('colorbox', plugins_url().'/amaltus-resources/js/colorbox/jquery.colorbox-min.js', array('jquery'), '20120101' );
	wp_enqueue_script('jquery-ui-1.8.18.custom.min', plugins_url().'/amaltus-resources/js/ui/jquery-ui-1.8.18.custom.min.js');
	wp_enqueue_script("jquery-ui-core", array('jquery'));
	wp_enqueue_script("jquery-ui-tabs", array('jquery','jquery-ui-core'));
	wp_enqueue_script("jquery.busy", plugins_url().'/amaltus-resources/js/jquery.busy.min.js', array('jquery'));
