    I think the misconception that $(( ... )) is a bashism is caused by
    the wrong highlighting defaults chosen by vim. To fix this add this to ~/.vimrc

    let g:is_posix = 1

    That will also allow you to use the $(command) POSIX construct.
    BTW, the vim syntax maintainers don't agree with changing this default:

    Pádraig.
