This can be extended to cover the case where a variable has two numbers
associated with it:

8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><
\version "2.20.0"
 
Movement.1.Staff.1 = { c d e }
Movement.1.Staff.2 = { c' d' e' }
Movement.2.Staff.1 = { f g a } 
Movement.2.Staff.2 = { f' g' a' } 
\score {
  <<
    \new Staff { \Movement.1.Staff.1 }
    \new Staff { \Movement.1.Staff.2 }
  >>

}
\score {
  <<
  \new Staff { \Movement.2.Staff.1 }
    \new Staff { \Movement.2.Staff.2 }
  >>

}

8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><

(cautionary note: I haven't examined the code or docs on this, but it
seems a dot before and after will do the trick mid-word and a single
dot at end of word)

A decade or so ago I resorted to converting all the numbers to Roman
numerals using a C routine that's knocking around on the interweb...
time I upgraded that.
