As mentioned in the chatterbox, you wanted to sort by the first element of the array rather than by the hash key. This example will work:
use strict;
use warnings;
my %hash = (
1 => [1, 'One'],
2 => [2, 'Two'],
3 => [3, 'Three'],
4 => [4, 'Four'],
5 => [5, 'Five'],
6 => [6, 'Six'],
12 => [12, 'Twelve'],
);
# sort the hash numerically by the first element in each array
foreach my $key ( sort { $hash{$a}[0] <=> $hash{$b}[0] } keys %hash )
{
print "Integer is: $key -- Alpha is: $hash{$key}[1]\n";
}
Please also note that if you had warnings turned on you would have realized the second element in your arrays are barewords and need to be quoted.

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).
