Thanks for your advice. I have done some detailed comparisons between the log of the successful repair (with UAC prompt) and the unsuccesful repair (without UAC prompt) and here are the unique lines for each case...
WORKING REPAIR: ============ MSI_LUA: Credential prompt not required, user is an admin Specifed source is not already in a list. Adding new sources is allowed. FAILING REPAIR: ========== MSI_LUA: Credential prompt is not required at this point, product is managed and deployment compliant Specifed source is already in a list. Adding new sources is not allowed. Machine policy value 'EnableUserControl' is 0 PROPERTY CHANGE: Modifying RestrictedUserControl property. Its current value is '0'. Its new value: '1'. There are many Machine Policy lines that are declared in greatly different orders, but are nominally identical, although some are duplicated in the failing repair.
