Changing ORDER BY

Hi All
win 2k pro sql 2k IIS 5 ASP-vbscript
I got a stored proc which basically returns a set of records depending
on a category ID (or all if passed ID =0) - see below
The FAQ Category below is retuned mostly order by Title but in some
other areas of my site I need to return it orded by CatID.
I was wondering whats the best way to do this as I cant seem to pass a
column name to the procedure and put "ORDER BY @.SortOrder"
These are the other ways I thought of.
1) create a new procedure the same with order by catID.
2) pass a number and use CASE - but I get error 1008
eg ORDER BY CASE WHEN @.Order=0 THEN Title ELSE CatID END
I can see this becoming a common problem so wouldn't like to do #1
above as that would require alot of maintence to keep them the same if
I changed any of the table design.
Thanks for any help.

CREATE PROCEDURE dbo.usp_Help_FindFAQCategoryByCatID
@.SelCatID TINYINT = 0
AS
SET NOCOUNT ON
-- Return all the FAQ Categories with Cat ID of the selected Category
SELECT CatID, ParentID, Title, FaqCount
FROM Help_FAQ_Categories
WHERE CatID= CASE WHEN @.SelCatID=0 THEN CatID ELSE @.SelCatID END
ORDER BY Title
GOTry
ORDER BY CASE WHEN @.sort = 'col1' THEN col1 END ASC,

it is almost correct. However, you cannot mix data types without
explicit conversions. The typical solution to this type of problem is to
use an ORDER BY column for each sort order:
ORDER BY CASE WHEN @.Order=0 THEN Title END,
CASE WHEN @.Order=1 THEN CatID END
