Why are criteria orderings receiving automatically a missing alias when adding to the QueryBuilder?

[ddegasperi]

When using Criteria together with the QueryBuilder I encountered the following limitation:

I tried to use a DQL function in the sort field of Criteria. When adding Criteria to QueryBuilder, an alias is automatically added to the sort fields where no alias exists. This leads to the DQL function being aliased and the query being translated incorrectly. If I use the DQL function via orderby of the QueryBuilder, the alias is not added automatically and it works.

Why is the alias automatically added to orderBy when using Criteria? Is there a special reason for this?
