Output:

$VAR1 = {
          'A' => {
                   '1' => 'a'
                 },

                   '4' => 'd'

          'E' => {
                   '5' => 'e'
                 },
          'C' => {
                   '3' => 'c'
                 },

                   '2' => 'b'

You can also use a for loop:

my %hash2;
for my $i (0 .. $#array1) {
    $hash2{ $array1[$i] }{ $array2[$i] } = $array3[$i];
}
