  :I did conider your edit summaries. I am aware of the other style guides, which are not unanimous on this point. There are some MOS standards that I never use elsewhere (periods and commas immediately after a close quotation marks make me cringe). However, Wikipedia should aspire to adhere to the MOS, especially in FAs. Furthermore, in this case ordinal numerals are more legible than the spelled out words. Thanks for not re-reverting 2 other editors who are trying to help.
