From what I gather you want everything numerical only up front, followed by anything with a letter in it sorted asciibetically. Here is some code using the ever popular Schwartzian Transform:
use strict;
use warnings;

my %keys;
@keys{('a'..'n')}= ('2','1','12','a12','a9',
   'a2b3','a2b4','b2b4','1a2','a2bb5',
   'a2bb5a','a2bb5b',654,9);

my @foo = map { $_->[0] }
  sort newsort
  map { [$_, $keys{$_} =~ /^(\d+)$/ ? ($keys{$_},1) 
                                    : $keys{$_}
        ]  
      } keys %keys;

print "KEY:$_  VALUE:$keys{$_}\n" foreach (@foo);

sub newsort {
  if ( defined $a->[2] and defined $b->[2] ){
    if ($a->[1] > $b->[1]) {return 1}
    return -1;
  }
  elsif ( defined $b->[2] or defined $a->[2]) {
    if ( defined $a->[2] ) { return -1 }
    return 1;
  }
  elsif ( $a->[1] gt $b->[1] ) { return 1; }
  elsif ( $b->[1] gt $a->[1] ) { return -1; }
  return 0;
} #newsort

__DATA__
KEY:b  VALUE:1
KEY:a  VALUE:2
KEY:n  VALUE:9
KEY:c  VALUE:12
KEY:m  VALUE:654
