A friend of mine once recieved a neck from Warmoth that had very significant 'bonus flame', when they very specifically wanted completely plain maple. We're in the UK, so returns are a huge pain to sort out, so I ended up taking the neck off their hands and they ordered a new neck from a different company, instead. Sometimes Warmoth give you figuring that's too good!
That said, if you have a specific look in mind—the way the grain is orientated, for example, can be very important to Les Paul fans—then I suggest either contacting Warmoth directly to seeing if they'll be getting any more wood in soon, or simply waiting another month or two. If you're prepared to spend the extra money to get a unique choice top, on top of however much you're spending on the body anyway, you can probably also afford to wait three or four weeks to see if a top you do like will come in, rather than taking a blind gamble. If you actually can get a piece of wood you like, you'll still be enjoying that guitar long after you've forgotten about the extra wait.
edit: and, for clarity, I have always followed my own advice and simply waited for a nice top to come in, so I can be sure i'm getting what I want. Even if Warmoth guaranteed AAAA figuring, one man's AAAA is another's AA, and even if you agree that the figuring is of a high enough grade, it may still have some aspect which is unappealing to you. It's your guitar and you're already paying a premium for it, so you may as well go all the way and be sure you're getting a top you like.
