Comment (by moeffju):

 For some additional explanation: PHP evaluates ternary operator
 expressions from left to right. Thus, for Plural-Forms like `nplurals=3;
 plural=n%10==1 && n%100!=11 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 ||
 n%100>=20) ? 1 : 2;`:

 for n = 1: (expected: 0, actual: 2)
 {{{
    1%10==1 && 1%100!=11 ? 0 : 1%10>=2 && 1%10<=4 && (1%100<10 ||
 1%100>=20) ? 1 : 2
 => TRUE && TRUE ? 0 : FALSE && TRUE && (TRUE || FALSE) ? 1 : 2
 => (TRUE && TRUE ? 0 : FALSE && TRUE && (TRUE || FALSE)) ? 1 : 2
 => 0 ? 1 : 2
 => 2
 }}}

 Parenthesizing the subexpressions fixes the precedence.
