Well, I've come across some maps where some slots have more than 1 weapon. For example the Equipment slot, where you can have mulitple grenades. Instead of the equipment slot, it is one and 2 where pistols and rifles are supposed to be.

ak_colt_warehouse, has in:
slot 1, AK47 and m4a1,
slot 2 Deagle and USP 9.0

Sometimes the bots crash, especially YaPB and I've encountered it long ago, finally thought of it. It's probably been dealt with, just giving an idea.
if(count(BOT_weaponSlot1()) > 1)

or I guess, something like that.
