How about
\score {
 { c d e }
 \midi{ pre = \tempo 4. = 70 }
}
?

(I.e., \tempo is a music expression => it's not a grammatical exception)

Semantics: If pre is set, then embed main input in a SequentialMusic when 
interpreting music for midi. So instead of interpreting { c d e } above, we 
interpret the expression:
{ \tempo 4.=70 { c d e } }
