You can't escape with backslashes inside a character class.
Put the minus at the end and drop all backslashes, unless you want to match \ .

A counterexample: 

c:\@Work\Perl\monks>perl -wMstrict -le
"my $s = 'abc\ZD+A-G\HJxyz';
 print qq{'$s'};
 ;;
 $s =~ m{ ([A\-Z\+GD]+) }xms;
 print qq{'$1'};
"
'abc\ZD+A-G\HJxyz'
'ZD+A-G'

(But I agree that putting the - at the end and dropping the backslashes would have the same effect.)

Give a man a fish:  <%-{-{-{-<
