I believe what you are trying to do is simply insert a custom field into a template? To do so, you just need to have the right php code in your template to grab the custom field:

http://codex.wordpress.org/Using_Custom_Fields

Should look like this:

<?php $key="score"; $result= get_post_meta($post->ID, $key, true); ?>
<p>Score: </p> <?php echo $result ?>

This code needs to be in a template and within the if (have_posts()) … section of code.

The plugin you are referencing is for creating custom fields and inserting them directly into a post or page, not a template.
