A few questions on technique:

1. Is there anything shorter than join'',?
2. What are some good sorting techniques?

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.

Is there anything shorter than join'',?

It depends. This:

    $"="";"@_"

is one character more than

    join"",@_

but if you have to do two joins,

    $"="";"@a";"@b"

is shorter than

    join"","@a";join"","@b"
