What's the field definition for your "title" field? Is it just string or are you doing some tokenizing?
It should be a string or a single token cleaned up (e.g. lower-cased) using KeywordTokenizer. In the example schema, you will normally see the original field tokenized and the sort field separately with copyField connection. In latest Solr, docValues are also recommended for sort fields.
