Order of digits in figured bass

There is a problem to determine the correct order of the digits in the figured 
bass.
I want the #3 under the 7.

%%%%%%%%%%   Begin example    %%%%%%%%%

\markup { \large "Bug in the horizontal order of the digits" }
\markup { \tiny "The #3 should be under the 7"  }


\version "2.12.0"

\relative c <<
 \new Staff {
  \time 2/4
  \clef bass
  d8 g, a4 |
  d,2 | \bar "|."
 }

 \new FiguredBass \figuremode {
  \override FiguredBass.BassFigure #'font-size = # -3 
  \set useBassFigureExtenders = ##t
  s8 <3- 6 5> <6 3+> <7 3+> |
  s2 |
 }
>>

%%%%%%%%%%   End example    %%%%%%%%%
