You can try to expand the value of \typescripthree with

\starttypescript[...][...][...]
     \expanded{\definefontsynonym[...][...][goodies=\typescriptthree]}
     \expanded{\definefontsynonym[...][...][goodies=\typescriptthree]}
\stoptypescript

or

\starttypescript[...][...][...]
     \startexpanded
         \definefontsynonym[...][...][goodies=\typescriptthree]
         \definefontsynonym[...][...][goodies=\typescriptthree]
     \stopexpanded
\stoptypescript
