If you set your scale settings to 1/64's and your text size to 7/64's if you then change your scale setting to 1/32's does the text size change to 1/8" or does it stay at 7/64th? If I identify the text it shows as 1/8".
It is still stored in the database as 7/64", but it's reported size is rounded to reflect the current scale precision. You can prove this by changing your scale precision back to 1/64's and returning to the Text menu or Identifying any text that was created at 7/64".
