OK, further tests show that the above patch is not working either:
System.Math::Round (double, int32, MidpointRounding) seems to always round to
even (another bug btwm but related).

      ldc.r8 float64(0x3FE0000000000000) //  load 0,5
      ldc.i4.0 // round with 0 decimals
      ldc.i4.1 // away from 0
      call float64 class [mscorlib]System.Math::Round (float64, int32,
valuetype [mscorlib]System.MidpointRounding)

gives 0, should be 1
