Help with rule for arranging cards within the same list when certain label is assigned

[Ashley Lawson]

I have added the following rule: 

when a card is added to the board by me, sort the list by label orange "Waiting on Something" ascending

What I have  is a list with multiple cards, maybe 10. I want to be able to add the label "Waiting on Something" when relevant, and whatever card I've added that to, pop to the top of my list. 

Said another way, my cards with this label are usually my top priority items, so I don't want to have to scroll down the list to find them. I need them on top, where I can see them, and get to them quickly. 

I added the above rule, and ONE of my lists updated on a board with several lists. The other lists did not rearrange my cards like I'm wanting. Am I doing something wrong? The rule makes sense to me, but when I'm changing the label, the card isn't auto-popping to the top like I need it to. Thanks for any help!

So is there no way for it to automatically do this for all lists, all the time? For every new one I create and every one I have already created? I would like this to be an infinite command.

You need the trigger to be

"when the orange "Waiting on Something" label is added to a card"

Also, you have to a new operation for each list. So if you had 4 lists you could have

"Sort the list #1 by label "Waiting on Something" ascending, Sort the list #2 by label "Waiting on Something" ascending, Sort the list #3 by label "Waiting on Something" ascending, Sort the list #4 by label "Waiting on Something" ascending,
