multiple sort not working if one field is datetime

[cgcullen]

I have this code which should sort by due date and then order number:

    <select
        class="jplist-select"
        data-control-type="sort-select"
        data-control-name="sort"
        data-control-action="sort">

          <option data-path="default">Sort</option>
          		<option data-path1=".sort_orderdue" data-path=".order" data-order1="asc" data-order="asc" data-type1="datetime" data-datetime-format="{month}/{day}/{year}" data-type="text">order number &#8593;</option>
          		<option data-path1=".sort_orderdue" data-path=".order" data-order1="desc" data-order="desc" data-type1="datetime" data-datetime-format="{month}/{day}/{year}"  data-type="text">order number &#8595;</option>
   </select>
