Extra sort field in LOV with Union

Question

I'm building an LOV that is based on a single table, but the list needs to be broken up into two groups to show preferred vs. non-preferred values. I would like to display the preferred values in the table first (sorted) and then the non preferred values (sorted) second. I am able to do this in SQL with a UNION and by creating an extra "sort" column for the ORDER BY clause. The problem is, Dynamic LOV only allows a query to return exactly two columns, hence I can't include my sort column. Below is the query that works in SQL Builder, but no LOV. Any suggestions on how I can do this in an LOV without including the 3rd column?
/* Preferred companies */
select     CC_COMPANIES.NAME||'*' as display_value,
     CC_COMPANIES.ID as return_value,
'A'||CC_COMPANIES.NAME as sort_value
from     CC_WATCHLIST CC_WATCHLIST,
     CC_COMPANIES CC_COMPANIES
where CC_WATCHLIST.ITEM_ID=CC_COMPANIES.ID
and CC_WATCHLIST.MEMBER_ID=:CC_MEMBER_ID
and      CC_WATCHLIST.CATEGORY_ID = 6
UNION
/* the rest of the companies */
select     CC_COMPANIES.NAME as display_value,
     CC_COMPANIES.ID as return_value,
'Z'||CC_COMPANIES.NAME as sort_value
from     CC_WATCHLIST CC_WATCHLIST,
     CC_COMPANIES CC_COMPANIES
where CC_COMPANIES.ID not in (select CC_WATCHLIST.ITEM_ID from CC_WATCHLIST where CC_WATCHLIST.MEMBER_ID=:CC_MEMBER_ID
and      CC_WATCHLIST.CATEGORY_ID = 6
and CC_WATCHLIST.ITEM_ID=CC_COMPANIES.ID)
ORDER BY sort_value

Jeff,
Try this:
select x.display_value, x.return_value from (
/* Preferred companies */
select CC_COMPANIES.NAME||'*' as display_value,
CC_COMPANIES.ID as return_value,
'A'||CC_COMPANIES.NAME as sort_value
from CC_WATCHLIST CC_WATCHLIST,
CC_COMPANIES CC_COMPANIES
where CC_WATCHLIST.ITEM_ID=CC_COMPANIES.ID
and CC_WATCHLIST.MEMBER_ID=:CC_MEMBER_ID
and CC_WATCHLIST.CATEGORY_ID = 6
UNION
/* the rest of the companies */
select CC_COMPANIES.NAME as display_value,
CC_COMPANIES.ID as return_value,
'Z'||CC_COMPANIES.NAME as sort_value
from CC_WATCHLIST CC_WATCHLIST,
CC_COMPANIES CC_COMPANIES
where CC_COMPANIES.ID not in (select CC_WATCHLIST.ITEM_ID from CC_WATCHLIST where CC_WATCHLIST.MEMBER_ID=:CC_MEMBER_ID
and CC_WATCHLIST.CATEGORY_ID = 6
and CC_WATCHLIST.ITEM_ID=CC_COMPANIES.ID)
ORDER BY sort_value) xJoel
