title: Sorting by second element of split array in liquid
body: <p>I am new to Liquid, so forgive me if this is obvious.</p>
  
  <p>I have some data whose titles are prefixed with A1, B10, C64, etc. before the real text I want to sort on, for example, "A1 Something" "B10 Nothing" "A23 Another".</p>
  
  <p>If I use</p>
  
  <pre><code>{% assign itemssorted = product.ds_related_products | sort: 'title' %}
  {% for item in itemssorted %}
  </code></pre>
  
  <p>then I get the items sorted according to the prefixes, whereas what I <em>want</em> is the items sorted by the text <em>after</em> the prefixes.</p>
  
  <p>Is there something like</p>
  
  <pre><code>{% assign itemssorted = product.ds_related_products | sort: 'title' | split: ' ' .... %}
  </code></pre>
  
  <p>I can use to implement this?</p>
