Or you can use PVars.
They are specific variables which can be set to a player and are NOT related to a specific script.
For example, in the gamemode if you do SetPVarInt(playerid, "Money", GetPlayerMoney(playerid));

In the filterscript you can do GetPVarInt(playerid, money);

It will return the same value as you set it in the gamemode.
