Maybe the problem is that you aren't checking exactly what you want to check... I'd suggest the following (full runnable code)

#!/usr/bin/perl
use warnings FATAL => 'all';
use strict;
my @cases = 1..19;
for my $case ( @cases ) {
    if (eval { interesting($case) }) {
        eval { process($case); };
        print "$case had processing errors: $@" if $@;
    } elsif ($@) {
        print "$case had interesting errors: $@";
    } else {
        print "$case not interesting.".$/;
        next;
    }
}
sub interesting {
    my $case = shift;
    die "random failure on interesting" if rand() > 0.7;
    return rand()>0.5?1:0;
}
sub process {
    my $case = shift;
    print "doing something with $case".$/;
    die "random failure on process" if rand() > 0.7;
}

Which gave me the following random output...

1 had interesting errors: random failure on interesting at /tmp/test.p
+l line 21.
2 had interesting errors: random failure on interesting at /tmp/test.p
+l line 21.
doing something with 3
4 had interesting errors: random failure on interesting at /tmp/test.p
+l line 21.
5 not interesting.
6 not interesting.
doing something with 7
8 not interesting.
9 not interesting.
doing something with 10
10 had processing errors: random failure on process at /tmp/test.pl li
+ne 28.
11 not interesting.
12 not interesting.
13 not interesting.
doing something with 14
14 had processing errors: random failure on process at /tmp/test.pl li

17 not interesting.
