Keyboard shortcut for Sort By Date Created
First make sure that date created is a visible column in list view in finder. You can do this by entering list view and right clicking the headers and checking date created. 

Then go to system preferences, keyboard, Shortcuts, and choose app shortcuts on the left. Then add a new shortcut for Finder by pressing the plus button and choosing finder from the drop down. In the menu title put "Date Created" exactly (without the quotes). Then focus the shortcut field and press your desired shortcut. For example Option+Command+8

Tested it in Mavericks and it works for me.
