It's lexical by default, not numerical.  From perldoc -f sort:

    # sort lexically
    @articles = sort @files;

    # same thing, but with explicit sort routine
    @articles = sort {$a cmp $b} @files;

$ cat foo.pl
#!/usr/bin/perl -lw

my @foo = ( 9, 15, 385, 2 );

print "Default: ", join( ", ", sort @foo );
print "cmp:     ", join( ", ", sort { $a cmp $b } @foo );
print "<=>:     ", join( ", ", sort { $a <=> $b } @foo );


$ perl foo.pl
Default: 15, 2, 385, 9
cmp:     15, 2, 385, 9
<=>:     2, 9, 15, 385
