How about 

my $test = {
            'record' => {
                                  'a' => 11,
                                  'b' => 22
                        }
          };

Or just: 

my $test;
$test->{record}->{'a'} = 11;
$test->{record}->{'b'} = 22;

If you want to initialize $test->{record} with something (and don't rely on autovivification), initialize it with {}.
