I wonder whether you’re using the wrong symbol, and using the correct 
one might help a little.  Your code is using the degree sign “°” U+B0, 
when by context this should probably be the masculine ordinal indicator 
“º” U+BA.

(Some fonts display this symbol as a superscript “o” like “ᵒ”; some add 
an underline to it like “̵ᵒ”; some add an underdot that I can’t easily 
imitate by abusing other Unicode characters; and your source material is 
using a full-stop “.” kerned in pretty tightly.)

I’m also pretty sure this is a font with old-style figures, where the 
numeral “1” looks like a small-caps “ɪ”; and so the v’s should be 
lower-case.

So the actual text should be “vº1º” & “vº2º” or “v.º1.º” & “v.º2.º”:

{
  c''1^\markup {
    \override #'(font-name . "TeX Gyre Schola")
    \override #'(font-features . ("onum"))
    { "vº1º2º" }
  }
  c''^\markup \concat {
    \override #'(font-name . "TeX Gyre Termes")
    \override #'(font-features . ("onum"))
    { "v." \hspace #-0.4 "º" "1." \hspace #-0.6 "º" "2." \hspace #-0.6 
"º" }
  }
}
