Like others have mentioned, this has nothing to do with the sortable() functionality. Instead you need to retrieve the items in the list, shift their positions and then clear and re-insert the list items again in their new order:

// Get your list items
var items = $('#mylist').find('li');

// The new index order for each item
var order = [4, 2, 0, 1, 3];

// Map the existing items to their new positions        
var orderedItems = $.map(order, function(value) {
    return items.get(value);
});

// Clear the old list items and insert the newly ordered ones
$('#mylist').empty().html(orderedItems);
