I think that appraoch will work but you might need to create your own array of locaitons and register it too. Maybe try something like this:

    while ($wp_alist = $vbulletin->db->fetch_array($wp_fulllist))
    {
        $locations[] = htmlspecialchars($wp_alist['location']);
        $wp_list[] = array(
            'id' => htmlspecialchars($wp_alist['id']),
            'name' => htmlspecialchars($wp_alist['name']),
            'locid' => htmlspecialchars($wp_alist['locid']),
            'location' => htmlspecialchars($wp_alist['location']),
            'url' => htmlspecialchars($wp_alist['url'])
        );
    }
    $locations = array_unique($locations);
    $templater->register('wp_list', $wp_list);    
    $templater->register('wp_locations', $locations);

and then in your template:

<vb:each from="wp_locations" value="location">
<h1>{vb:raw location}</h1>
	<vb:each from="wp_list" value="list">
	<vb:if condition="$list['location'] == $location">
	<tr>
		<td>{vb:raw list.location}</td>
		<td><a href="{vb:raw list.url}">{vb:raw list.name}</a></td>
	</tr>
	</vb:if>
	</vb:each>
</vb:each>

I'm not sure of there's any way to use the value from the outer vb:each to specify the inner vb:each array. That would make things a little more efficient.
