That's a pretty interesting one!
perl looks like the most appropriate choice for this:
Code:
#!/usr/bin/perl -w
while (<>) {
  if (/^([^\d\.]*)(\d*)([^\d.]*)\.([^\.]+)$/) {
    if ($1) { print "$1" }
    if ($2) {
      $val=$2+1;
      print $val;
      $suffix="";
    } else {
      $suffix="2";
    }
    if ($3) { print "$3" }
    if ($suffix) { print "$suffix" }
    print ".$4";
  } else {
    print "# Could not parse the following line:\n";
    print "$_";
  }
}
