suggestion: garage list by column headers

I wanted to be able to order the garage listing by clicking the column headers...
So I have modified my template
ACP -> Look & Feel -> Template -> skin_garage -> itemList
I have replaced the "<tr class='header'>...</tr>" with the next code:

<tr class='header'>
<th scope='col' class='short' style='width:1%;'>{$this->lang->words['thumbnail']}</th>
<th scope='col'>
<if test="$this->request['orderby'] == 'make_name'">
<if test="$this->request['orderhow'] == 'desc'">
<a href='{parse url="do=item_list&amp;orderby=make_name&amp;orderhow=asc" base="publicWithApp"}' title='{$this->lang->words['order_by']} {$this->lang->words['vehicle_name']} {$this->lang->words['in']} {$this->lang->words['ascending_order']}' style='text-decoration: none;'>{$this->lang->words['vehicle_name']} {parse replacement="sort_up"}</a>
<else />
<a href='{parse url="do=item_list&amp;orderby=make_name&amp;orderhow=desc" base="publicWithApp"}' title='{$this->lang->words['order_by']} {$this->lang->words['vehicle_name']} {$this->lang->words['in']} {$this->lang->words['descending_order']}' style='text-decoration: none;'>{$this->lang->words['vehicle_name']} {parse replacement="sort_down"}</a>
