Two Blocks for sort filter Views -- Drupal 7
I dun really get what you mean. I presume you are trying let admin or user to able to do sorting. 

I have two ideas

Under format change from unformatted list to table. At this case you are able to do sorting by click table header. 

Another one is under sort criteria, add any content you want to sort and select expose.

If I wrong, can show me any example??
