I combined Zaxo's answer and dws's answer to get something that worked quite nicely for me, and avoided the ugly return from redo unless.

#!/opt/perl5/bin/perl -w

use strict;

my @instances; my $i;
my $selection = 0; my $j = 0;

opendir OPHOME, "/opt/lnpsite" or die "Can't open /opt/lnpsite: $!\n";
my @files = sort(readdir(OPHOME));
closedir OPHOME;

foreach(@files){
    if (m/(op|nm)\d{2}$/) {
        push(@instances, $_);
    }
}

my $length = scalar(@instances);

while ($j != 1) { &chooser( \@instances ); }

open CHOSENENV, ">chosen_setup_env";
print CHOSENENV "$instances[$selection]";
close CHOSENENV;

sub chooser {
    $i = 1;
    my ($arrayRef) = @_;
    print "\nAvailable Instances\n===================\n";
    foreach(@$arrayRef) { print "  $i. ",$_,"\n"; $i++; }
    print "\nSelect an instance and press enter: ";
    $selection = <>;
    chomp($selection);
    $selection -= 1;

    if ($selection < -1) {    #!~ m/[1-$length]/) {
        print "\nIncorrect selection.  Try again.\n";
    } elsif ($selection > $length) { # !~ m/(\d{1})?/) {
        print "\nIncorrect selection.  Try again.\n";
    } else { $j = 1; }
}
