【VBS】 Clarification on How the System Determines Rule Priority

【What we would like to know】
We would like to understand how the system determines the priority for the rules in Visual Builder Studio.
Specifically, by what setting or configuration does the system decide which rule takes precedence?

【Back ground】
We have configured two rules for the "Note to Receiver" field (see attached screenshots):

• Rule① (CP#19 Note to Receiver – For Indonesia):
  Condition applied only for the specific (Indonesia) BUs (40003_BU, 40022_BU, 40024_BU, 40051_BU)
