Use the RANDOM function, in a switch, or you could use nested random statements.

Note very few people use AEL and I had to do some looking up, which I might have got wrong.

AEL is great fun! Here are some examples using random key word in AEL.

TIL switch has a pattern.

6

random != equal – but it is probably ‘good enough.’

Increment with modulo (or an if statement) may be another avenue.

Also, what to do if a gateway is busy?

7

you can set dialplan like this with function RAND:
exten => s, n, Set(randgw=${RAND(1,2,3)})
…
and then ExecIf() …

The OP is using AEL, so whilst one probably could use ExecIF, it would be mixing to different ways of coding conditional execution.
