I was getting into some heavy culling and wanted to find a way to sort down to ONLY those raw files that were untouched.  No tweaks and no crops.

I built a custom sorting preset like this and it seems to be doing the trick:

Start by opening your Library Filter, and then your fields should be:
1) Dates: All
2) Cameras: All
3) Lens: All
4) Label: All (1 Label .. Nothing should have a color)
Add Column
5) File Type: RAW
Add Column
6) Develop Preset: Default Settings

Save this as a Custom Library File and it can be applied to any folder in any catalog!

Set up your sort per the above columns, and you should be left with nothing but unedited raw files ready to cull some more!

Bonus: If you DO see a stray file listed in another row of info, chances are pretty good that it's either a file you meant to flag as a PICK or a file you meant to flag as a REJECT.

What this also does is allow you to simply walk through a folder with the P or X keys and as you choose which way to go, the files vanish from your screen.  Then you can go back and sort by PICK or REJECT and either work on the Picks or blow out the Rejects in one go!
