When formatting a number into a string use "%d" not "%s". Also,

pawn Код:

if(sscanf(params,"ds[64]",id,time,reason)) return SendClientMessage(playerid,GRAY,"CMD: /ajail <playerid> <minutes> <reason>");

Should be:

pawn Код:

if(sscanf(params,"uds[64]",id,time,reason)) return SendClientMessage(playerid,GRAY,"CMD: /ajail <playerid> <minutes> <reason>");

You forgot to put the "u" parameter for playerid.
