Maybe it's better to show a complete typescript:

\definefontfallback [cyrillic_regular]    [name:dejavuserif]           [cyrillic]
\definefontfallback [cyrillic_bold]       [name:dejavuserifbold]       [cyrillic]
\definefontfallback [cyrillic_italic]     [name:dejavuserifitalic]     [cyrillic]
\definefontfallback [cyrillic_bolditalic] [name:dejavuserifbolditalic] [cyrillic]

\starttypescript [serif] [schola]
  \setups [font:fallback:serif]
  \definefontsynonym [Serif]           [name:texgyreschola-regular]    [fallbacks=cyrillic_regular]
  \definefontsynonym [SerifBold]       [name:texgyreschola-bold]       [fallbacks=cyrillic_bold]
  \definefontsynonym [SerifItalic]     [name:texgyreschola-italic]     [fallbacks=cyrillic_italic]
  \definefontsynonym [SerifBoldItalic] [name:texgyreschola-bolditalic] [fallbacks=cyrillic_bolditalic]
\stoptypescript

\starttypescript [schola]
  \definetypeface [\typescriptone] [rm] [serif] [schola]       [default]
  \definetypeface [\typescriptone] [ss] [sans]  [latin-modern] [default]
  \definetypeface [\typescriptone] [tt] [mono]  [latin-modern] [default]
  \definetypeface [\typescriptone] [mm] [math]  [latin-modern] [default]
\stoptypescript
