llSetPayPrice trouble

I'm toying with llSetPayPrice and ran into a head-scratcher (at least for me). I ran the following code, denying permission_debit, and as predicted the llSetPayPrice triggered. However, with I reset the script and tried to grant permission, it still ran through the code with ELSE (the llSay was triggered). Even commenting-out all the appropriate code, it still will not reset llSetPayPrice. Any thoughts?

-Frank

default //Set everything up
{
state_entry()
{
llRequestPermissions(llGetOwner(),PERMISSION_DEBIT); // Allow llGiveMoney
// integer perm = llGetPermissions();
// if (perm & PERMISSION_DEBIT) // check if permission has been granted
// {
//llSay(0, "Permission Granted";
// }else
// {
// llSetPayPrice(PAY_HIDE, [50, PAY_HIDE, PAY_HIDE, PAY_HIDE]);
//llSay(0, "Permission NOT granted";
// }

requesting permissions is not a synchronous command (it does not hold up script execution) and llSetPayPrice sets a prim attribute.

default //Set everything up
{
	state_entry()
	{
		llRequestPermissions(llGetOwner(),PERMISSION_DEBIT ); // Allow llGiveMoney
	}
	run_time_permissions(integer perm)
	{
		if (perm & PERMISSION_DEBIT) // check if permission has been granted
		{
			llSetPayPrice(PAY_DEFAULT, [PAY_DEFAULT, PAY_DEFAULT, PAY_DEFAULT, PAY_DEFAULT]);
			llSay(0, "Permission Granted");
		}
		else
		{
			llSetPayPrice(PAY_HIDE, [50, PAY_HIDE, PAY_HIDE, PAY_HIDE]);
			llSay(0, "Permission NOT granted");
		}
	}
}
