ID Records who have an MQL Date before an Order Date

Hey Marketo world - 

Question for you guys: I'm attempting to pull people that MQLed before an order.

I have MQL Date and I have Order Date, however it's a relative relationship. I would like MQL Date to be BEFORE Order Date. Been racking my head to come up with a way to do this and am currently at a loss. Wanted to reach out to the greater collective here to see if anyone else has run into this before or has any ideas on ways to pull this type of information. 

Thanks in advance all!
