Thomas pointed out one of the new SQL features in 8i (ORDER BY inside a view). However you did not use this kind of construct in your query, so this is not where you query would fail in pre-8i releases.
You used another new 8i SQL feature that was not allowed in earlier release: the use of a select clause in a column list:
SELECT col1, col2,
(SELECT colx FROM ... WHERE ...) -- this is only allowed in 8i
FROM ...
