AFAIK, the main reason is to handle multi-valued fields.
The need to sort partially stems from the fact that the Document class
does not explicitly handle multi-valued fields.

Solr must also sort/hash the Document returned from Lucene because of
this lack of ability to represent a field with multiple values.

Perhaps this is something that should be fixed in Lucene 3, along with
the input/output document issues (documents you get back shouldn't
have things like boosts)?
