Try this to sort, search, etc
Here's the key to be able to search for and sort by the last name, first name, organization, etc, with the Droid Incredible...
Your Search button (Magnifying Glass icon) in the plastic area below the touch screen, must be set up properly.
Here's how: From any of the Home Screens, touch the Magnifing Glass on the bottom right of your phone... You should then see a Google Search box at the top of the screen and a keyboard at the bottom...
Now click on the word Menu, next to the Home button...
Search Settings will come on the screen, touch it...
Under Searchable Items, make sure the only option checked is People...
Then, from any of the Home Screens, touch that Magnifing Glass and start typing in that Google Search box at the top of the screen - and your People contacts will start showing up...
Slide the keyboard off the bottom of the screen to see your contacts...
Touch on the contact to view the info, make the call, send a message, email, etc.
Works for me...
Hope it helps.
