Getting earliest date from created/modified

Hi guys
I'm not sure if this has been asked before, however a quick search doesn't seem to show any really relevant answers to my questions. I did find one previous thread that actually asked this question but didn't get an answer, but it's old now and I'm not sure if the answer has been implemented (or if there's always been a way and I'm just not seeing it).
What I'm currently doing is getting Hazel to file my images for me in folders based on YEAR > MONTH. What I've noticed though in consolidating my images from disparate sources to one central place, is that the created date seems to be changed to today's date (or whichever date the file was moved), but the modified date retains the original date of the file. BUT, any new photos I take are automatically put into my new central repository.
I'm trying to work out if there's a way to get the oldest date of the file from either created or modified, then use that for the folder structure. My current rules are working fine, except when I have photos from 5 years ago being put into this month's folder. If someone has seen this answered elsewhere, please do point me in the direction of the answer, otherwise I'm hoping someone may have an answer. (Mr Noodle?)
Cheers in advance!
