I know this doesn't really answer your question, but in any real world situation, for this type of problem I'd generally solve the two criteria separately for maximum re-usability and adaptability.

Data::Validate has more robust implementations of both of these functions

if ( is_integer($value) && is_between_inclusive($value,0,100) ){
  ...
}

sub is_integer{
  my $value = shift;
  return $value =~/^[-]?\d+$/;
}

sub is_between_inclusive{
  my ($value,$min,$max) = @_;
  return(($value >= $min) && ($value <= $max));
}
