Want wp_get_post_terms return in arbitrarily order, how to do?

add_filter('the_content','my_function');
function my_function($content){
    the_post_thumbnail('thumbnail', array('class' => 'top-post-img' ));

  if (is_single() && in_category('5')){
    global $post;
    $term_list = wp_get_post_terms ($post->ID,'school',array('fields'=>'names'));
    ?>
    <div id="some_class">
    <span>School:<strong><?php print_r($term_list[0]); ?></strong></span>
    <?php
    if (is_single() && in_category('5')){
        $term_list = wp_get_post_terms ($post->ID,'article',array('fields' =>'names'));
        ?>
        <span>Article:<strong><?php print_r($term_list[0]); ?></strong></span>
        <?php
        if (is_single() && in_category('5')){
            $term_list = wp_get_post_terms ($post->ID,'teacher',array('fields'=>'names'));
            ?>
            <span>Teacher:<strong><?php print_r($term_list[0]); ?></strong></span>
            </div>
            <?php
            return $content;
            }
        }
    } else {
        return $content;
    }
}

Thanks to suggestions made by Rarst, this code works like a charm.
As you can see, it does show the Featured Image which belongs to that post,
and the output is returned in exact order as wished in the code.
It also uses some CSS to style (in the style.css) so it shows nice below
the title and above the content.

Update
Getting Notice: Undefined offset: 0

Anyone around to help me out?
