Say I have the following:

• Post IDs: 1,2,3,4,5,6,7,8,9,10
• Category: A, B, C, D, E

I want to create

• A page that will contain Taxonomy A and have the following Post IDs in the following order: 4, 6, 3, 8, 9
• A page that will contain Taxonomy B and have the following Post IDs in the following order: 5, 1, 3, 4, 3

Anyway to go about this? I can't use order / orderby here, no?
