I do not beleive the sort box anywhere in the program is language dependant since the sort table descriptions are in English in the database. If this indeed is what you are talking about.
But you agree with me that the options in the select box should be language dependent as all texts that are displayed to the end user?
I think it would be sufficient to add language strings for earch order option to the language file as slightly alter the check which one has been choosen.
