In version 1.2.7 the ability to navigate shops was implemented this is how you would go about doing this. Just put this command in and put the shop name where you would like it to navigate to, the shop.

Slot1:
    ItemID: 272
    ItemAMT: 1
    TokenCost: 0
    Command: openTokenServer %Player% ShopName
    GiveItem: false

Make sure GiveItem is false and TokenCost is 0, you don't want to charge players or give them items for navigation. Also remember to replace ShopName with the name of the shop it is going to.

This is how you would format it for the Vault shops:

Slot1:
    ItemID: 272
    ItemAMT: 1
    TokenCost: 0
    Command: openMarketServer %Player% ShopName
    GiveItem: false

Also, you may want to add some lore to explain where it goes, or a name works too! Check here how the new lore system works! http://dev.bukkit.org/bukkit-plugins/tokenshop/pages/shop-creation/shop-lore-usage/
