Sort behaviour

I see strange results when sorting with -n options and I wander if somebody can explain it.

Input file and two results:
Code:
  
$ cat aa
14
-1
  
11
-1
  
0
-1
  
0
$ sort -u aa
  
-1
0
11
14
$ sort -u -n aa
-1
  
11
14
$

As you can see, zero disappeared when I used -n option. Why is that?

NAME
Net::LDAP::Control::SortResult - Server Side Sort (SSS) result control object SYNOPSIS
use Net::LDAP::Control::Sort; use Net::LDAP::Constant qw(LDAP_CONTROL_SORTRESULT); use Net::LDAP::Util qw(ldap_error_name); $sort = Net::LDAP::Control::Sort->new( order => "cn -age" ); $mesg = $ldap->search( @args, control => [ $sort ]); ($resp) = $mesg->control( LDAP_CONTROL_SORTRESULT ); if ($resp) { if ($resp->result) { my $attr = $resp->attr; print "Problem sorting, ",ldap_error_name($resp->result); print " ($attr)" if $attr; print " "; } else { print "Results are sorted "; } } else { print "Server does not support sorting "; } DESCRIPTION
"Net::LDAP::Control::SortResult" is a sub-class of Net::LDAP::Control. It provides a class for manipulating the LDAP sort request control 1.2.840.113556.1.4.474 as defined in RFC-2891 A sort result control will be returned by the server in response to a search with a Server Side Sort control. If a sort result control is not returned then the user may assume that the server does not support sorting and the results are not sorted. CONSTRUCTOR ARGUMENTS
attr If "result" indicates that there was a problem with sorting and that problem was due to one of the attributes specified in the sort control. "attr" is set to the name of the attribute causing the problem. result This is the result code that describes if the sort operation was sucessful. If will be one of the result codes describes below. METHODS
As with Net::LDAP::Control each constructor argument described above is also available as a method on the object which will return the current value for the attribute if called without an argument, and set a new value for the attribute if called with an argument. RESULT CODES
Possible results from a sort request are listed below. See Net::LDAP::Constant for a definition of each. LDAP_SUCCESS LDAP_OPERATIONS_ERROR LDAP_TIMELIMIT_EXCEEDED LDAP_STRONG_AUTH_REQUIRED LDAP_ADMIN_LIMIT_EXCEEDED LDAP_NO_SUCH_ATTRIBUTE LDAP_INAPPROPRIATE_MATCHING LDAP_INSUFFICIENT_ACCESS LDAP_BUSY LDAP_UNWILLING_TO_PERFORM LDAP_OTHER SEE ALSO
