views are not just stored queries. A view is much more like a database table then a stored query. Since tables and relational sets in general, do not have ORDER, order by not only doesn't make sense on them -- it is not allowed in the language.
In order for a client applicatoin using a SELECT to be gauranteed to get the data in sorted order -- that application must apply the order by clause.
