This can be solved with a special case of the Schwartzian Transform. How do I sort an array by (anything) 
use strict;
use warnings;
my %pos2base2bin = (
    '315' => { '8'  => 0 },
    '329' => { '6'  => 0 },
    '352' => { '5'  => 0 },
    '390' => { '1'  => 0 },
    '280' => { '7'  => 1 },
    '360' => { '9'  => 0 },
    '349' => { '4'  => 0 },
    '305' => { '10' => 0 },
    '380' => { '3'  => 1 },
    '251' => { '2'  => 0 }
);



my @file1 =
    map {$_->[1]}
        sort {$a->[0] <=> $b->[0]}
            map {[each %$_]} 
                values %pos2base2bin;


$"= "\t";
print "file1 @file1\n";
