Personally, I would simplify this more by removing the dependence on the $i variable. It is fine to have $i in the code for outputting, but if you want to remove it later you can be sure not to introduce bugs:
my $i = 0;
foreach my $hash ( @AoH_sorted ) {
# Swap these for start with 0
$i++;
print "$i\t";
foreach my $key ( keys %{$hash} ) {
print "$key\t";
}
print "\n";
}

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).
