Custom Field Schedule

I’m trying to create a daily schedule on my site using Custom Fields. I want Custom Fields to display the time (7:00pm), and I want to sort the loop based on time from 12:00am and up to 11:59pm. How can I sort based on my time custom field? I’ve been able to display the content but i can’t figure out how to sort it. This is the code I’m using so far.

<ul>
<?php 

query_posts(array('post_type'=>'page', 'orderby'=>'meta_value_num','order'=>'ASC','post__in' => array(122,124,197,212,113,126,217,111,120,130,118,224,96,116), 'showposts'=>18, 'post_parent'=>93));
?>
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<li class="views-row">
<div class="views-field-phpcode">
 <span class="field-content">
<a href="<?php the_permalink(); ?> target="_blank" title="<?php printf( esc_attr__( 'Permalink to %s', 'twentyten' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a>
</span>
<span class="field-content">
<?php $customField = get_post_custom_values("Host");
if (isset($customField[0])) {
    echo $customField[0];
}
?>
</span>
</div>
<div class="views-field-field-event-date-value">
 <span class="field-content">
 <span class="date-display-single">
<?php $customField = get_post_custom_values("Scheduled Time");
if (isset($customField[0])) {
    echo $customField[0];
}
?>
</span>
</span>
</div>
 </li>
<?php endwhile; ?>
</div>
<?php wp_reset_query(); ?>
<?php else : ?>
sorry nothing here.
<?php endif; ?>
</ul>
