Fixes wrong usage of getSelect()->order() method

[sreichel]

Fixed order() methods where direction is used as (non-existing) second parameter.

https://github.com/OpenMage/magento-lts/blob/1.9.3.x/lib/Zend/Db/Select.php#L577-L587

/**
 * Adds a row order to the query.
 *
 * @param mixed $spec The column(s) and direction to order by.
 * @return Zend_Db_Select This Zend_Db_Select object.
 */
public function order($spec)
{
    if (!is_array($spec)) {
        $spec = array($spec);
    }

Used $ grep -rn "order('[a-z_]*'," ./app/code/core/Mage/ ... so that should be all.
