Problem with meta_value order after update

Try WP_Query() instead of query_posts()

$args = array(
   'posts_per_page' => 10,
   'meta_key' => 't_count',
   'orderby' => 'meta_value_num',
   'order' => 'ASC'
 );

// The Query
$the_query = new WP_Query( $args );

// The Loop
while ( $the_query->have_posts() ) :
    $the_query->the_post();
    echo '<li>' . get_the_title() . '</li>';
endwhile;

// Restore original Query & Post Data
wp_reset_query();
wp_reset_postdata();

Above code should work!
