Found it! In my tests I made the same mistake you did. The declaration should be

DECLARE INTEGER RegEnumValue IN Win32API;
  INTEGER hKey, INTEGER dwIndex,;
  STRING @lpValueName, INTEGER @lpcValueName,;
  INTEGER <b>lpReserved</b>, INTEGER @lpType,;
  STRING @lpData, INTEGER @lpcbData

Both of us passed the lpReserved parameter by reference rather than value. Change the declaration and it should work fine.
