DB error "no such field" when executing actions on a sorted contact search result with search profile

Steps to reproduce:

• Create a profile with e.g. the postal code field of the primary address
• Perform a contact search using this profile for displaying the results
• Sort the result by the postal code field
• Tick the "all # records" radio button
• Choose any action to perform on the result (e.g. "Print PDF document")

The result is a "DB error: no such field" for the "1-postal_code" field. Error details:

)

The generated query is missing the JOINs for the civicrm_address table, resulting in the postal_code field not being part of the result set to be ordered by. The JOIN is not being added to the query in CRM_Contact_BAO_Query::prepareOrderBy() due to the field being named 1-postal_code and the code expects the field being named postal_code for adding relationships to the civicrm_address table.

The exception is being raised in CRM_Contact_BAO_Query::searchQuery.

Stepping through the code, this seems to also happen when ordering the search result, but the exception is then being caught in CRM_Contact_Selector::fillupPrevNextCache(), following a $this->rebuildPreNextCache() call to re-create the query.
