One way to do it: 

#!/usr/bin/perl

my @list = ('a', '6', '5', '5', '4', '5', '0', 'e');

my $hex = join '', @list;

my $bin = unpack("B*", pack("H*", $hex));  # "101001100101010101000101
+00001110"

my $idx = -1;
my @tuner_list = map {$idx++; $_ ? $idx : ()} reverse split //, $bin;

print "@tuner_list\n";  # 1 2 3 8 10 14 16 18 20 22 25 26 29 31
