I had started off with lower-case Roman numerals, but that gives a

best solution is probably to use upper case C and D (and M, probably),
and lower case i, v, x and l, so that 1,444 would be MCDxliv. That
doesn't look too bad, and should keep me, Lilypond and Scheme all
happy.
A lone Roman numeral as a variable name seems a little terse to me. You
might consider adding a prefix that more fully describes what the thing
is. For example, PsalmCLLLVI is more descriptive than just CLLLVI.
With a new* enough LilyPond, you can even do Psalm.136 to use Arabic
numerals.

\Foo.1234

There are some edge cases where the parser currently does not like the
".key" syntax, but a little escaping seems to do the trick as a
temporary workaround:

\markup \box \column { \FooMCCLLLIV ##{ \Foo.1234 #} }

Just something to consider.
