That goal is secondary and can be dispensed with. It is OK to use a symbol that 
one must remember or look up. 'unordered-or' is simply too ungainly.

Of the names you suggest, 'alt' is the the best. But here's another idea: use 
'|' for unordered or, and 'or' for ORdered OR. Strictly speaking this would be 
an incompatible change, but I doubt whether many users will notice or care.
