I've got multiple divs, each with an ordered list (various lengths). I'm using jquery to add a class to each list item according to its index (for the purpose of columnizing portions of each list). What I have so far ...
<script type="text/javascript">
/* Objective: columnize list items from a single ul or ol in a pre-determined number of columns
1. get the index of each list item
2. assign column class according to li's index
*/
$(document).ready(function() {
$('ol li').each(function(index){
// assign class according to li's index ... index = li number -1: 1-6 = 0-5; 7-12 = 6-11, etc.
if ( index <= 5 ) {
$(this).addClass('column-1');
}
if ( index > 5 && index < 12 ) {
$(this).addClass('column-2');
}
if ( index > 11 ) {
$(this).addClass('column-3');
}
// add another class to the first list item in each column
$('ol li').filter(function(index) {
return index != 0 && index % 6 == 0;
}).addClass('reset');
}); // closes li .each func
}); // closes doc.ready.func
</script>
... succeeds if there's only one list; when there are additional lists, the last column class ('column-3') is added to all remaining list items on the page. In other words, the script is presently
indexing continuously through all subsequent lists/list items, rather than being re-set to [0] for each ordered list.
Can someone please show me the proper method/syntax to correct/amend this, so that the script addresses/indexes each ordered list anew?
many thanks in advance.

p.s. the markup is pretty straight-up:
<div class="tertiary">
<h1>header</h1>
<ol>
<li><a href="#" title="a link">a link</a></li>
<li><a href="#" title="a link">a link</a></li>
<li><a href="#" title="a link">a link</a></li>
</ol>
</div><!-- END div class="tertiary" -->
