civicrm_contact_search() ignores $params values

civicrm_contact_search() is intended to handle the following values in its $params array:

$otherVars = array( 'sort', 'offset', 'rowCount' );

however, because of a syntax error it ignores them.

simple fix is to replace array_key_exists() with in_array() about 13 lines into the function
