Is random order possible for module output?

Hmm… I’m not able to get this to work. Has anybody had success doing this?

I’ve tried sorting by a non populated field in the module insertion tag and that didn’t seem to change anything. I thought perhaps it was because I was using the collection object type, so I tried @Adam.Wilson previously suggested method for sorting collecitons [Bug] If module items have weighting then sorting by other fields doesn't work

That didn’t seem to work for me either. Here’s my code inside the collection layout (I’m sorting by an unpopulated field in this case as well):

<div class="swiper-container">
    <div class="swiper-wrapper">
 {% assign sorted = this.items | sort: 'Author' %}       
{% for slide in sorted %}
{% if slide.ItemTags contains 'home' %}
        <div class="swiper-slide">
            <div class="hero__image" style="background-image: url('{{slide['Image']}}');"></div>
            <img class="hero__image-placeholder" src="{{slide['Image']}}" style="opacity: 0;">
            <div class="hero__title-wrapper">
            <p class="hero__title"><span class="hero__supertitle">{{slide['SuperTitle']}}</span> <br/>{{slide['Description']}}</p>
            </div>
        </div>
{% endif %}
{% endfor %}
    </div>
    <div class="swiper-pagination"></div>
</div>
