combining Better Anchor Links and scroll script

I would like to combine Better Anchor Links and a scroll script like the one used here: https://ngnf.no/medlemsbedrifter/ (click on one of the links at the top of the page contents to see what I mean).

This works by adding the following script:

<script type='text/javascript'>

jQuery(document).ready(function($) {

	$(".scroll").click(function(event){
		event.preventDefault();
		$('html,body').animate({scrollTop:$(this.hash).offset().top}, 500);
	});
});

</script>

and adding a class=”scroll” to all the anchor links.

I would like to make this same effect work in combination with Better Anchor Links but that doens’t seem to work. What I did is the following:

• add the script to each page
• hack the plugin so that each link gets a class=”scroll”

Nothing happens. Anyone a clue?
