That is not very efficient code. Here's my stab at your approach:

use 5.14.2;
use warnings;

$| = 1;

print "Range bottom > ";
chomp (my $from = <STDIN>);

print "Range top    > ";
chomp (my $to   = <STDIN>);

$from =~ m/^\s*(-?\d+)\s*$/ or die "Invalid range";
$from = +$1;
$to   =~ m/^\s*(-?\d+)\s*$/ or die "Invalid range";
$to   = +$1;
$from <= $to                or die "Invalid range";

my $range_length = $to - $from + 1;

my @points = map { $from + int rand $range_length } 1 .. 100;
say "@points";
