Numeric variables evaluated as strings in expressions

Super confused here. I'm writing a function to load with .murex_profile, and I want it to execute differently based on whether an argument is passed into it. Ultimately, if it does not receive one and only one argument, it should prompt the user (me) to make a selection from fzf. Either the argument from stdin or the selection from fzf should then be assigned to a variable for the rest of the function to use. I've tried about a million things, and I've run through the documentation until I'm cross-eyed. Here's a few super minimal examples of what I'm trying to do:

❯ function test {
2 » $PARAMS -> count -> set arg_count
3 » out $arg_count 
4 » $arg_count == 1
5 » out
6 » exitnum
7 » }

❯ test foo
1
false
0
❯ test foo bar
2
false
0

I think I understand that $PARAMS is json? The docs seem to suggest that count should do what I want:

Counts the number of items in a structure, be that a list, map or other object type.

And it looks like that's what it's doing, but then the comparison isn't doing what I expect it to?

❯ ja [bar] -> set jarray
❯ $jarray -> count
1

❯ $jarray -> count -> set jarray_count
❯ $jarray_count == 1
false

Thinking I might be running into some kind of data type issue, I tried casting explicitly to JSON, and I think this is how to do that?

❯ function test {
2 » tout json $PARAMS
3 » }
❯ test foo
[
    "foo"
]
❯ function test {
2 » tout json $PARAMS -> count
3 » }
❯ test foo
1
❯ function test {
2 » tout json $PARAMS -> count -> set arg_count
3 » $arg_count == 1
4 » }
❯ test foo
false

What am I missing? Waving the white flag.
