Please provide sample code that proves the flaw that your pull request addresses does actually happen - I still can't reproduce it. See below:

$ php test.php 
/home/kguest/dev/code/Services_Openstreetmap/examples/test.php:28:
array(5) {
  'barrier' =>
  string(9) "lift_gate"
  'bicycle' =>
  string(3) "yes"
  'foot' =>
  string(3) "yes"
  'motorcar' =>
  string(3) "yes"
  'motorcycle' =>
  string(3) "yes"
}
/home/kguest/dev/code/Services_Openstreetmap/examples/test.php:30:
array(6) {
  'barrier' =>
  string(9) "lift_gate"
  'bicycle' =>
  string(3) "yes"
  'foot' =>
  string(3) "yes"
  'motorcar' =>
  string(3) "yes"
  'motorcycle' =>
  string(3) "yes"
  'horse' =>
  string(3) "yes"
}
$ cat test.php 
<?php    
$version = '@package_version@';
if (strstr($version, 'package_version')) {
    set_include_path(
        dirname(dirname(__FILE__)) . PATH_SEPARATOR . get_include_path()
    );
}

require_once 'Services/OpenStreetMap.php';

$osm = new Services_OpenStreetMap();

$node = $osm->getNode(401839334);
var_dump($node->getTags());
$node->setTag('horse', 'yes');
var_dump($node->getTags());
