Another option, easier to read but slower than ikegami's solution: 
sub stripCtrls {
  my $text = shift;

  #changed capture of $1 as per moritz
  $text =~ /(<\/Mil[^>]*>)([^\x9D]*)\x9D/;
  my $sStartTag = $1;
  my $sBetweenTags = $2;

  $sBetweenTags =~ s/[\x90\x8F]//g;
  return "$sStartTag$sBetweenTags\x9D";
}

which you can call like this stripCtrls($sTaggedText).

And if you don't need to preserve \x90 and \x8F in the start tag, maybe you might try the even simpler $text =~ s/[\x90\x8F]//g?

Best, beth

Update: put in sub so can be used as one liner
