I'm sorry but I don't understand how you could order something by a value
(last day of month).

you can only order things by a field (e.g. a date field) or fields, in
increasing or decreasing order. 

e.g.:

you can do:

SELECT id,eventdate FROM mytable ORDER BY eventdate DESC;

and not:

SELECT id,eventdate FROM mytable ORDER BY '2000-01-31' DESC; 

the latter one doesn't mean anything to me, nor to SQL I suppose.
