one of those tests is the "CAST" test, which for sqlite actually  
doesnt matter much since sqlite doesnt have much need for CAST.  the  
sqlite dialect detects the version that does not support cast and  
skips producing that clause.

the "order by" stuff is more severe and relates to versions of sqlite  
where ordering doesnt work for the complicated nested queries that  
SA's eager loading produces.
