and (how) can I reference previous outputs? I can name them beforehand
but if I do it is lots more to type. Using screen or gdm to copy the
value is not better either.

in my experience orpie is nice just because it needs very few key
strokes (no parentheses, no return, short forms for most extended
functions) like on a real calculator. GNU Emacs Calculator is similar,
but a bit larger (and much more powerful). But that does not mean orpie
is powerless, it has arbitrary-precision integers and matrices as well
(I am missing fractions in orpie, but can live without, since gcd is
there; so I can do all fraction calculations "manually").

You need not. In the particular case I solved it with BartPE and there
will probably be lots of more grml releases before I need it again
(using striped volumes on Windows is not very common). Okay, I hope to
never need it again, (I would not mind never needing grml again
either...) but you never know. ;)
