it may not work but have you tried just adding so= within the display link?
<a href="$db_script_link_url&$db_key=$rec{$db_key}&view_records=1&ww=1&so=1">$rec{'FieldName'}</a>
I know the Top 10 by Gender allows sorting by a specific field but it also states that there should be more than 3 options to use this method. So adding a list of alpha fields to sort by using that means wouldn't work.
