Query multiple taxonomy in Custom Post Type

There’s the “tax_query” argument available since the latest wp release:

global $query_string;
$args['tax_query'] = array(
    array(
         'taxonomy' => 'status'
        ,'terms'    => array( 'available', 'pending' ) // change to "sold" for 2nd query
        ,'field'    => 'slug'
    ),
);
$args['post_type'] = 'listing';
parse_str( $query_string, $args );

$avail_n_pend = query_posts( $args );

if ( $avail_n_pend->have_posts() ) : 
    while ( $avail_n_pend->have_posts() ) : 
    $avail_n_pend->the_post();
    // show result
    the_title();
    endwhile; 
endif;

// use this for testing:
/*
echo '<pre>'; 
    print_r($GLOBALS['wp_query']->tax_query); 
echo '</pre>';
*/

// rewind for second query
rewind_posts();

// second_query
$args['tax_query'] = array(
    array(
         'taxonomy' => 'status'
        ,'terms'    => array( 'sold' )
        ,'field'    => 'slug'
    ),
);
parse_str( $query_string, $args );

$sold = query_posts( $args );

if ( $sold->have_posts() ) : 
    while ( $sold->have_posts() ) : 
    $sold->the_post();
    // show result
    the_title();
    endwhile; 
endif;
