Isn't this better addressed with using Grid and an explicit setting for 
Alignment? The following gives me something that looks good enough for me:

Style[
  Grid[{
    {NumberForm[1000*N@Pi, {5, 2}]},
    {NumberForm[N@Pi, {5, 2}]},
    {NumberForm[N[Pi] 10^-1, {5, 2}]}
   },
   Alignment -> {"."}
   ],
  FontFamily -> "Helvetica"
  ]
