GulpJS, не работает сортировка

Почему он собирает файлы (в каком-то своем) случайном порядке, а не как перечислено в order()?

var gulp = require('gulp'),

    concat = require('gulp-concat'),

    order = require("gulp-order"),

    uglify = require('gulp-uglify');



gulp.task('scripts', function () {

    gulp.src('pack-js/*.js')

        .pipe(order([
            "pack-js/acc.common.js",

            "pack-js/acc.userlocation.js",

            "pack-js/acc.track.js",

            "pack-js/acc.cms.js",

            "pack-js/acc.product.js",

            "pack-js/acc.refinements.js",

            "pack-js/acc.storefinder.js",

            "pack-js/acc.carousel.js",

            "pack-js/acc.autocomplete.js",

            "pack-js/acc.pstrength.js",

            "pack-js/acc.password.js",

            "pack-js/acc.minicart.js",

            "pack-js/acc.pickupinstore.js",

            "pack-js/acc.orderapproval.js",

            "pack-js/acc.langcurrencyselector.js",

            "pack-js/acc.paginationsort.js",

            "pack-js/acc.checkout.js",

            "pack-js/acc.address.js",

            "pack-js/acc.refresh.js",

            "pack-js/acc.stars.js",

            "pack-js/acc.forgotpassword.js",

            "pack-js/acc.productDetail.js",

            "pack-js/acc.producttabs.js",

            "pack-js/acc.variantdetails.js"

        ]))

        .pipe(concat('build.common.js'))

        .pipe(uglify())

        .pipe(gulp.dest('js'));

});



gulp.task('default', function() {

    gulp.run('scripts');



    gulp.watch('pack-js/**', function(event) {

        gulp.run('scripts');

    })



});
