Force tuplet number above notes

[Knute Snortum]

I am trying to get both tuplet numbers above the notes in the following code.  I've tried \override TupletNumber.direction = #UP, but evidently this does not work.  What's the correct way to do this?

\version "2.19.55"

\language "english"

\relative {

  \omit TupletBracket

  \override TupletNumber.direction = #UP

  \tuplet 3/2 2 { <ef' a gf'>4-> <ef a f'>-> <ef a e'>->

    <ef a ef'>-> <ef a df>-> <ef a c>-> }

}
