Yo can either use global command overrides:

For example in admin_overrides:

"sm_giveweapon" "o"

Then anyone with the o flag can use that command

or groups with specific command access:
http://wiki.alliedmods.net/Adding_Groups_(SourceMod)
For example in admin_groups:

Groups
{
	"Donators"
	{
		"flags"		"o"
		Overrides
		 {
			"sm_giveweapon"		"allow"
		 }
		
	}
}

Then anyone with the Donators group would get the o flag and gain access to that command, even with the command retaining it's default access flag.
