An order that I'm probably going to toss out first.

It's the ever-so popular order of cyan, orange, blue, purple, green, yellow.

Which was chosen based on the order the SOULs appear in Photoshop Flowey's battle.

That's literally it. (Though this also matches the order of increasing strength of items.)

I see no reason why Flowey's order should match the real order, especially when we take into consideration that Flowey wasn't around to know what the real order actually is.
