I may help you with your first problem:

This under your SetPlayerScore in OnPlayerDeath where you set the score higher:

pawn Код:

dUserSetINT(PlayerName(playerid)).("score",GetPlayerScore(playerid));

And this to your login command:

pawn Код:

SetPlayerScore(playerid,dUserINT(PlayerName(playerid)).("score")+GetPlayerScore(playerid));

And it saves to your scriptfiles with a player name
