Looking for information on how the hierarchy logic works when using conditional formatting on multiple columns.

Example: In Customer Order, the planned ship date background should turn red if the date is in the past. If the status is Invoiced/Closed, the entire line should be greyed out. Right now the Planned ship date turns red on Invoiced/Closed lines. How do I make the Status trump the Planned Ship Date formatting?
