My hope with the test conditions was that if $score was null/undefined (say from a timeout), it would fail the numeric tests, and trigger the undefined answer. Obviously that isn't the case. In the general sense $score should be a number and come up with an exit code of 0, 1, or 2, but I don't test to be certain the $score is numeric. Maybe that would be the preferred case, if $score is undefined, immeidately exit with exit code 3. Seems that is a good way to handle it, thanks for your insight! If you're ever in the NYC area, I owe you a beer! This code exits as I had hoped: 
#!/usr/bin/perl -w
use strict;

my $radio = $ARGV[0];
my $warnrate = $ARGV[1];
my $critrate = $ARGV[2];
my $line = `/usr/bin/snmpwalk -v1 -c PTsnmp $radio .1.3.6.1.4.1.5454.1
+.40.2.4.0`;
if ($line eq '') {
print "snmpwalk returned nothing, timeout likely occurred.\n";
exit 3
}
if ($critrate > $warnrate) {
print "Make sure your critical value is less than or equal to your war
+ning value.\n";
exit 5
}
if ($critrate <= $warnrate) {
        my @values = split(' ', $line);
        my $score = $values[3];
        if ($score > $warnrate) {
            print "OK, rf is $score. \|Mbps=$score\n";
                exit 0
            } elsif (($score <= $warnrate) && ($score > $critrate)) {
            print "WARNING, rf is $score. \|Mbps=$score\n";
                exit 1
            } elsif ($score <= $critrate) {
            print "CRITICAL, rf is $score. \|Mbps=$score\n";
                exit 2
            } 
}
