Using Data Store to save Specific scripts for a player?

Is there a way to save scripts that a player has bought. (This may sound weird but im about to explain it). In my game the things you can purchase are abilities. Instead of the abilties being tools they are local scripts that are activated by pressing the "E" key. Anyway is there a way of transforming this script (which enables you to purchase things with R$) into a script that saves the items a player has purchased in game with leader-board stats such as "cash".

productId = 19372077 

local MarketplaceService = Game:GetService("MarketplaceService")
function UsernameFromID(ID)
 if type(ID) ~= "number" then
 return
 end
 local sets = game:service("InsertService"):GetUserSets(ID)
 for k, v in next, sets do
 if v.Name == "My Models" then
 return v.CreatorName
 end
 end
end
function giveRewards(player)
 -- do stuff you want to do here, using the variable player for the player that clicked it. To access the character, do player.Character.
 return Enum.ProductPurcaseDecision.PurchaseGranted
end
MarketplaceService.ProcessReceipt = function(receiptInfo)
 giveRewards(UsernameFromID(receiptInfo.PlayerId))
end
script.Parent.MouseButton1Down:connect(function()
 Game:GetService("MarketplaceService"):PromptProductPurchase(script.Parent.Parent.Parent.Parent, productId)
end)

[Im trying to make a cool game but the only thing holding me back from releasing it to the public is data store :(]
