Sorting Files via downloaded Date

Ok...either I cant figure this out or this option dosent exist and ill be semi pissed

In a lot of folders, I want this option but ill explain it via Leopards downloads folder. So we have the Downloads folder where items we download via the space time continuum are held. I would like to have the items via downloaded date so for other folders, most recently added. NOT created because the item might have been created 2 weeks ago and not modified cause lord knows, me just opening it means ive modified it.

Am I insane? Please Help
