[Orgmode] wish list: sort tasks by age

[Christopher League]

I would love to be able to sort TODOs by their age, so it becomes  
painfully obvious what I have been ignoring.  Since org relies on free- 
form text (a strength), it's tricky to ensure that every item gets a  
'creation-time' property.  But it doesn't need to be accurate to the  
second; even a script that added that property once every day or so  
might do the trick.

Since I commit my agenda files to git every day or so, I can actually  
get an approximation to this with git-blame... grep the TODO  
headlines, then sort by commit date.  It's pretty hackish, and I'm not  
sure I want to go to the trouble of integrating that raw data with the  
agenda view, if there's a better way within org.

Ideas? Thanks!
Chris
