You need to tell compadd by passing -V plus the name of a group of
matches.  I think

  compadd -V unsorted - $revarray

ought to be good enough.  While I'm at it,

  compadd -V unsorted -a revarray

is a little more efficient if the array is big.

(It's not too hard to make this use the usual tags mechanism to mix with
other completions but it doesn't sound like you actually need that.)
