Comment (by pramsey):

 No, your answer is wrong, it's not an ordering problem, it's a "getting it
 wrong" problem, but why your platform, that I dunno.
 {{{
 select st_distance(
   'GEOMETRYCOLLECTION(LINESTRING(0 0,1 1),LINESTRING(5 5,4 4),LINESTRING(0
 0,-1 -1),POLYGON((0 0,4 0,4 4,0 4,0 0)))',
   'GEOMETRYCOLLECTION(LINESTRING(6 6,7 7))'
 );

 The failing test is a "cluster within" with a tolerance of 1.4, so the two
 elements fall outside the tolerance and should be in different clusters,
 as the platforms that succeed (all of them but one) return.
