That's an interesting point, but I don't see it as a show-stopper. Either  
you allow it to have the wrong numbers while loading, or you make reverse  
ordered lists block layout for a while, or we could use something along  
the lines of:

    <ol count-down-from="6">

...which is more of a pain to author but at least can render correctly

Instructions are seldom put in reverse order. ;-)
