I tested this on my WinXP 32 bit machine. It works fine. Something is wrong with your command line, what I don't know. But there is no fundamental need to escape the " characters. A side effect of a Windoze command line could be true.

#!/usr/bin/perl
use warnings;
use strict;

my %accounts = (
  tom =>  "BigApple",
  tom2 => "BigApple2",
  tom3 => "BigApple3",
  tom4 => "BigApple4",
  tom5 => "BigApple5",
  tom6 => "BigApple6",
  tom7 => "BigApple7",
);
# sort the users in descending order
my $counter = 1;
for my $userID (reverse sort keys %accounts) {
  print "$userID\t";
  print "\n" if $counter++ % 3 == 0;
}

__END__
Prints:

tom7    tom6    tom5    
tom4    tom3    tom2    
tom

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
