The line var parentItem = el.parent().parent(); was getting the wrong level in my code. I commented out the second parent which now works.
I also added the ability to get the previous child item prevSibling: el.prev().data('id')
This allows me to move a tree of items up and down in the one level and also between levels.
Sample HTML
<ol class="dd-list" data-id="ITEM-ID">
<li class="dd-item" data-id="ITEM-ID">
<div class="dd-handle">
ITEM-NAME
</div>
</li>
<li class="dd-item" data-id="ITEM-ID">
<div class="dd-handle">
ITEM-NAME
</div>
</li>
</ol>
