Displaying Custom Fields data by Category

Hi,

Can anyone help me display a list of blog posts by category along with custom field data. Basically each post on my blog has a custom field which is either “Plus” or “Negative” and I want to display this information alongside the post name sorted by category. For example:

Category One
PostOne “Plus”
PostTwo “Minus”

Category Two
PostThree “Plus”
PostFour “Plus”

So far I have come up with the following code on a custom page:

<?php
    $catList = new WP_Query();
    $catList->query('year=$current_year');
    while ($catList->have_posts()) : $catList->the_post();
?>
<!-- LOOP STUFF HERE -->

<ul>
		<?php
		global $customFields;
		$customFields = "'Plus', 'Minus'"; //Comma seperated 's1', 's2', 's3'
		$customPosts = new WP_Query();
		add_filter('posts_join', 'get_custom_field_posts_join');
		add_filter('posts_groupby', 'get_custom_field_posts_group');
		$customPosts->query('showposts=25' );//Uses same parameters as query_posts
		remove_filter('posts_join', 'get_custom_field_posts_join');
		remove_filter('posts_groupby', 'get_custom_field_posts_group');
		while ($customPosts->have_posts()) : $customPosts->the_post();
		$plus = get_post_custom_values("Plus");
		$minus =  get_post_custom_values("Minus");
		?>
<li>
<?php echo $plus[0]; ?>
<?php if ($minus[0]){ ?>
-<?php echo $minus[0]; ?>
<?php } // this ends the IF ?>
  <a href="<?php the_permalink() ?>" rel="bookmark"> <?php the_title(); ?></a>
(<?php the_time('F Y'); ?>)
</li>
    <?php endwhile; ?>
</ul>
<?php /* End Custom Field Posts */ ?>

    </li>
</ul>

<?php the_category(',') ?>
<?php endwhile; ?>
