That is correct. But other tools do this easily.

I suggest using awk for this. It is a standard tool that will do
exactly what you are asking.
$ echo one two three four | awk '{print $3,$1,$2}'
three one two
$ echo one two three four | awk '{print $3,$2,$1,$2}'
three two one two
Using awk just seems perfectly fitted to these types of tasks.
