The date field is specified as:
<fieldType name="date" class="solr.DateField" sortMissingLast="true"
omitNorms="true"/>
And it's used as a dynamic field:
<dynamicField name="date_*" type="date" indexed="true" stored="true" />
Nothing in this configuration has changed since 4.6.1.
Sorting on other values, like integers and text, works fine. Only date fields
are a problem.
