My "job" here is one to moderate- and if there is something questionable, I will call it out. You were rather evasive in your posts..
Like others have said, we have no clue why you cannot pick it when its upside down.. you should be able to.
Probably just has something to do with the way your holding your picks and/or the angle..
Sorry I cannot be of more assistance. I would suggest unlocking it with the key, and working on it while it is not locked to an object.
Can you remove the mattress from the top bunk, and "flip" the lock upward facing? If you don't have the key, may be your only option, short of dismantling the bed as you already stated.

I've been nothing if not forthcoming and honest with you, and all it has earned me (from the mod staff, anyway) is derision and mistrust. I am severely disappointed.
You may want to click on the "page 1" button and re-read this post from the beginning, I am not the only one who was (in your own terms) unhelpful...
Don't know what else your expecting.. people have already given you some really good advice, it sounds like you expect some "magic trick" or "trade secret" we don't have to give to you on how to pick this..
