Instead, the dialogue only refers to numbered photon torpedoes and IMHO suggests that torpedoes 2, 4 and 6 had a yield that's different from torpedoes 1, 3 and 5 which is the reason why Kirk specifically wanted to have those fired.
Sure, Kirk was specific which torpedoes he wanted but there isn't anything to preclude it from being shorthand for torpedo 2 in tube 2, torpedo 4 in tube 4 and torpedo 6 in tube 6.
What is the ambiguity anyway? The numbering of torpedoes do not exceed the number of tubes used in "Elaan".
It would have been more interesting if Kirk said, ready torpedo 21, 45 and 67.
