title: Gremlin query for sorted results starting from result with specified string attribute
body: <p>I have some vertices in my graph with String attributes called someAttribute, example 4 vertices with different &quot;someAttribute&quot; values:</p>
  <pre><code>someAttribute = &quot;aaa&quot;
  someAttribute = &quot;bb1&quot; 
  someAttribute = &quot;c&quot; 
  someAttribute = &quot;d&quot;
  </code></pre>
  <p>I sorted it using sort() by &quot;someAttribute&quot; and I need to query for vertices with attribute greater than &quot;c&quot; (so I expect vertices with attribute &quot;d&quot; in results), but it looks like gt predicate expects a number. How can I achieve it with String attribute?</p>
  <pre><code>traversal.order().by(&quot;someAttribute&quot;)
                      .has(&quot;someAttribute&quot;, gt(&quot;c&quot;))
                      .range(0, 2);
  </code></pre>
