Sorry about that bibu, I didn't see page 2 for some reason and that this has already been resolved. Exolents function will do just fine, the only thing I think you have wrong is the window of time for pruning entries. Correct me if I'm wrong, I'm a little rusty.
PHP Code:
nvault_prune_key(g_score_vault, szDeathKey, get_systime(), 86400 * get_pcvar_num(amx_death_expire_days))
Start: get_sys_time() = Now
End: 86400 * days = Days to remove in seconds (which is days starting from 01/01/1970 or w\e).
Should be
Start: 0 (01/01/1970)
End: get_systime() - ( get_pcvar_num( amx_death_expire_days ) * 86400 ) ) (Now - X days)
