Sorting Posts by a Custom Field

I have a post template which displays the custom fields of all posts within a category as tabular data — think of a sports team roster page

How can I control the sort order of the posts coming in?

I want to sort by the player’s number

<!-- GET ANY POSTS ASSIGNED WITH THE CUSTOM FIELD PLAYER-SPORT THAT EQUALS VOLLEYBALL -->
<?php query_posts('meta_key=player-sport&meta_value=wbb');  ?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>

				<?php $playerfirstname = get_post_meta($post->ID, 'player-first-name', true); ?>
				<?php $playerlastname = get_post_meta($post->ID, 'player-last-name', true); ?>
				<?php $playeryear = get_post_meta($post->ID, 'player-year', true); ?>
				<?php $playerposition = get_post_meta($post->ID, 'player-position', true); ?>
				<?php $playernumber = get_post_meta($post->ID, 'player-jersey-number', true); ?>
				<?php $playerhometown = get_post_meta($post->ID, 'player-hometown', true); ?>
				<?php $playerheight = get_post_meta($post->ID, 'player-height', true); ?>
				<?php $playerimage = get_post_meta($post->ID, 'player-image', true); ?>
				<?php $playerhighschool = get_post_meta($post->ID, 'player-highschool', true); ?>

				<tr>
					<td><a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><?	if($playerimage) : ?><img src="<? echo $playerimage ?>" alt="Yavapai College <? echo $playeryear ?> <? echo $playerfirstname ?> <? echo $playerlastname ?>" title="Yavapai College <? echo $playeryear ?> <? echo $playerfirstname ?> <? echo $playerlastname ?>" width="100" style="border:2px solid #333;"></a><?php endif; ?></td>
					<td><a style="color:blue; text-decoration:none; border-bottom:1px dotted blue; font-weight:bold;" href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><? if($playerlastname) : ?>&nbsp;<? echo $playerlastname ?><?php endif; ?>, <?	if($playerfirstname) : ?><? echo $playerfirstname ?><?php endif; ?></a></td>
					<td><? if($playernumber) : ?><? echo $playernumber ?><?php endif; ?></td>
					<td><? if($playeryear) : ?><? echo $playeryear ?><?php endif; ?></td>
					<td><? if($playerposition) : ?><? echo $playerposition ?><?php endif; ?></td>
					<td><? if($playerheight) : ?><? echo $playerheight ?><?php endif; ?></td>
					<td><? if($playerhometown) : ?><? echo $playerhometown ?><?php endif; ?></td>
					<td><? if($playerhighschool) : ?><? echo $playerhighschool ?><?php endif; ?></td>
