In general it's not supported, but simple hack can enable this: http://jsfiddle.net/ztRF5/132/ (note: required is latest version from github).

// mapping between SVG attributes and the corresponding options
Highcharts.seriesTypes.bar.prototype.pointAttrToOptions.dashstyle = 'dashStyle';

var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container',
        type: 'bar'
    },
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },
    plotOptions: {
        bar: {
            stacking: 'percent'   
        }
    },
    series: [{
        data: [29.9],
        borderColor: 'black',
        borderWidth: 2,
        dashStyle: 'dash'
    }, {
        data: [13] 
    }]
});
