code:

$b = Doctrine::getTable("CheAttribute")>createQuery("A2")>leftJoin("A2.CheItemAttribute IA2 WITH IA2.item_id = ?", 2)>addOrderBy("A2.sort_order ASC")>execute();

var_dump($b[0]>getCheItemAttribute()>getAttrValue());

$tb = Doctrine::getTable("CheAttribute")>createQuery("A")>leftJoin("A.CheItemAttribute IA WITH IA.item_id = ?", 1)>addOrderBy("A.sort_order ASC")>execute();

var_dump($tb[0]>getCheItemAttribute()>getAttrValue());
exit();

in browser i see:

string '10' (length=2)

string '10' (length=2)

but expected:

10

123

With hydration Array & Scalar hydrated data is ok.
