This gives a hint about what it is about: The syntax of \score is:
\score {
<music expression>
<optional paper, header, layout and midi blocks>
}
Since "a b" is two separate expressions, while {a b} is one expression, only
the latter one is OK.
You could say that in \score { { a b } }, the inner braces have a very
different meaning than the outer ones.
