Ye, in the plugin I gave you create a new file called rankings_compile_stats.php with the following content further below.
It will display on category view: Rank # overall
And on overall view will display: Rank # in category
Place {$rank_overall} and {$rank_category} in the following files where you want the text to appear
table_row.html, table_top_row.html, table_row_premium.html, table_top_row_premium.html
	
	
	
		PHP:
	
	
		// This tag is empty on overall ranking
$TMPL['rank_overall'] = '';
// This tag is empty on category ranking
$TMPL['rank_category'] = '';
if ($TMPL['cat_exist'])
{
    // This code runs on category page
    $rank_overall = 1;
    $rank_result = $DB->query("SELECT sites.username FROM {$CONF['sql_prefix']}_sites sites, {$CONF['sql_prefix']}_stats stats WHERE sites.username = stats.username AND active = 1 ORDER BY {$order_by}", __FILE__, __LINE__);
    while (list($username) = $DB->fetch_array($rank_result))
    {
        if($username == $TMPL['username'])
        {
            break;
        }
        $rank_overall++;
    }
    $TMPL['rank_overall'] = "Rank {$rank_overall} overall";
}
else
{
     // This code runs on the overall page
    // Escape users category
    $category_rank_sql = $DB->escape($category_raw, 1);
    $rank_category = 1;
    $rank_result = $DB->query("SELECT sites.username FROM {$CONF['sql_prefix']}_sites sites, {$CONF['sql_prefix']}_stats stats WHERE sites.username = stats.username AND active = 1 AND category = '{$category_rank_sql}' ORDER BY {$order_by}", __FILE__, __LINE__);
    while (list($username) = $DB->fetch_array($rank_result))
    {
        if($username == $TMPL['username'])
        {
            break;
        }
        $rank_category++;
    }
    $TMPL['rank_category'] = "Rank {$rank_overall} in {$TMPL['category']}";
}
