Hi, with some help from WP.org I managed to sort this out yesterday. For the record, the final code that we ended up using is the following:

text/x-generic page-10787.php 
PHP script text
<?php get_header(); ?>

<section class="content">

	<?php get_template_part('inc/page-title'); ?>

       <div class="pad group">

<div class="entry">
						<div class="entry-inner">
							<?php the_content(); ?>
							<?php wp_link_pages(array('before'=>'<div class="post-pages">'.__('Pages:','hueman'),'after'=>'</div>')); ?>
						</div>
						<div class="clear"></div>
					</div><!--/.entry-->

<?php

$posts = get_posts( array(
    'numberposts' => -1,
    'meta_key' => 'elokuvat_l',
    'order'=> 'ASC'
) );

if( $posts ) {
	echo '<ul>';
		$temporary_list = array();
		foreach( $posts as $post ) {
			$film_names = get_field( 'elokuvat_l', $post->ID );
			$film_names_array = preg_split( '/\r\n|\r|\n/', $film_names );
			foreach( $film_names_array as $film_name ) {
				$temporary_list[] = array( 'post_id' => $post->ID, 'film_name' => $film_name );
			}
		}
		// custom sort function
		usort( $temporary_list, function ( $a, $b ) {
			return strcasecmp($a['film_name'], $b['film_name']); // compare two strings ignoring case
		});
		// loop and display
		foreach( $temporary_list as $film_name ){
			echo '<li><a href="' . get_permalink($film_name['post_id']) . '">' . $film_name['film_name'] . '</a></li>';
		}
	echo '</ul>';
}

?>

	</div><!--/.pad-->

</section><!--/.content-->

<?php get_sidebar(); ?>

<?php get_footer(); ?>
