Sort by payload value

[John Davis]

Hello,

We are trying to use payload values as described in [1] and are running
into issues when issuing *sort by* payload value.  Would appreciate any
pointers to what we might be doing wrong. We are running solr 6.6.0.

* Here's the payload value definition:

   <fieldType name="delimited_payloads_float" stored="true" indexed="true"
class="solr.TextField">
      <analyzer>
          <tokenizer class="solr.PatternTokenizerFactory"
pattern="[A-Za-z0-9][^|]*[|][0-9.]+" group="0"/>
          <filter class="solr.DelimitedPayloadTokenFilterFactory"
encoder="float"/>
          <filter class="solr.LowerCaseFilterFactory"/>
      </analyzer>
  </fieldType>

* Query with sort by does not return documents sorted by the payload value:

{
  "responseHeader":{
    "status":0,
    "QTime":82,
    "params":{
      "q":"*:*",
      "indent":"on",
      "fl":"industry_value,${indexp}",
*      "indexp":"payload(industry_value, 'internet services', 0)",*
      "fq":["{!frange l=0.1}${indexp}",
        "industry_value:*"],
*      "sort":"${indexp} asc",*
      "rows":"10",
      "wt":"json"}},
  "response":{"numFound":102668,"start":0,"docs":[
