Installation order sub categories

Hi,

and thank you for your plugin. Two notes:

1.
“Optionally set ‘orderby’ => ‘term_order’, ‘order => ‘ASC’ to manually sort queries by this order.”

‘order should be ‘order‘

2.
When ordering sub taxonomies and using

$args = array('orderby' => 'term_order', 'order' => 'ASC');
    $ordered = wp_get_object_terms($post_ids, 'taxonomy',$args);

term_order in sub categories overlaps parents order

<select><option value="">Tipologia</option>
<option data-or="0" value="5">Appartamento</option>
<option data-or="1" value="29"> - miniappartamento</option>
<option data-or="1" value="8">Casa indipendente</option>
<option data-or="2" value="30"> - bicamere</option>
<option data-or="2" value="20">Casa in linea</option>
<option data-or="3" value="31"> - tricamere</option>
<option data-or="4" value="32"> - quadricamere o più</option>
<option data-or="4" value="13">Villa</option>
<option data-or="5" value="14">Villa a schiera/Villa bifamiliare</option>
<option data-or="10" value="37">capannone</option>
<option data-or="11" value="36">negozio</option>
<option data-or="12" value="35">ufficio</option>
<option data-or="13" value="34">Terreno</option>
</select>

data-or is term_order, as you can see options are ordered by term_order AND (not what i want) alphabetically and there are dupplicates in term_order

Maybe correct output should be (as in backend)

<select><option value="">Tipologia</option>
<option data-or="0" value="5">Appartamento</option>
<option data-or="1" value="29"> - miniappartamento</option>
<option data-or="2" value="30"> - bicamere</option>
<option data-or="3" value="31"> - tricamere</option>
<option data-or="4" value="32"> - quadricamere o più</option>
<option data-or="5" value="20">Casa in linea</option>
<option data-or="6" value="8">Casa indipendente</option>
<option data-or="7" value="13">Villa</option>
<option data-or="8" value="14">Villa a schiera/Villa bifamiliare</option>
<option data-or="9" value="37">capannone</option>
<option data-or="10" value="36">negozio</option>
<option data-or="11" value="35">ufficio</option>
<option data-or="12" value="34">Terreno</option>
</select>

Any clue?
