In your statement
   (}. - }:)^:order list
the value represented by 'order' becomes a part of the derived
verb which receives the value represented by 'list'.

In contrast, with
   order (}. - }:)@]^:[ list
your top level verb takes two arguments.

In other words, you put the number represented by 'order' in
one of two different places because you are doing different things
with it.

Does this help?
