OK...so far...

You really don't need to do this...

              ^^^^^^

huh?  it doesn't look like a string to me...

foo = []
foo.push(0)
foo[0] += 1
p foo

output:

[1]

I'm confused.  Why do you think you're operating on a string?  Even if
it is a string, this looks like a quick way to get what you want:

foo = []
foo.push("0")
foo[0].succ!
p foo

output:

["1"]

So, for your variables, you would want:

@adaptations[@lastQueryNum].timesUsed[count] += 1

and that's it.  unless I'm missing something.
