   Odd, but I wondered the same thing myself today.  Harry didn't
know about the AK curse yet, but even if he did know about it at that
point, he wouldn't have been able to perform the curse. According to
FakeMoody in GOF, even if the entire class of fourth year students 
tried the AK curse on him, he doubted that he'd get a nosebleed.  
This certainly supports that Harry, alone, wouldn't have been able to 
do the AK the year before.  If there is another killing curse, I'm 
unaware of it.  But more importantly, it seems that Harry was unaware 
of it. 

However, I think it's important to remember Harry's state of mind at 
that point.  Perhaps he hadn't considered that he really didn't know 
how to kill Sirius; he only knew that he wanted to and that he had 
the opportunity.  Perhaps he just didn't get far enough along in his 
(tortured) though process to realize, "Duh -- I don't know how to 
kill him!" before Lupin arrived.

Going way out on a limb, maybe Harry thought that he could shoot fire 
or an electrical type current from his wand into Sirius's heart?  
Really far out there:  could he have "transfigured" his wand into a 
weapon such as a knife?  Or, once a wand, always a wand???
