Try this:

local previous_key = previous_key or nil
local walls_array = {     
    [1] = {positions = {Position(5989, 6041, 7), Position(5989, 6041, 7)}, itemid = 1271},
    [2] = {positions = {Position(5989, 6041, 7)}, itemid = 1271},
    [3] = {positions = {Position(5989, 6041, 7)}, itemid = 1271},
}

function onThink(interval)
    local random_key
    repeat
        random_key = math.random(#walls_array)
    until random_key ~= previous_key

    local wall_array = walls_array[random_key]
    for _, position in pairs(wall_array.positions) do
        local tile = Tile(position)
        local wall = tile and tile:getItemById(wall_array.itemid)
        if wall then
            wall:remove()
            for _, targetPlayer in ipairs(Game.getPlayers()) do
            targetPlayer:sendTextMessage(MESSAGE_EVENT_ADVANCE, "INSERT MESSAGE HERE")
            end
            addEvent(function(position, itemid)
                Game.createItem(itemid, 1, position)
            end, interval, position, wall_array.itemid)
        end
    end
    previous_key = random_key
    return true
end
