example:
#1  set index_format="%4C %Z %{%Y-%b-%d} %-23.23F|%4c|%X|%s"
#2  set index_format="%4C %Z %{%Y-%b-%d} %-23.23F|%4c|%?X?%X& ?|%s"

in example #1 the number of attachments (%X) is simply put
after the message size (%4c) and before the subject (%s).
however, most of these simply show a "0".  pretty boring.

example #2 uses "%?X?%X& ?" which uses "%?" as a conditional.

this sequence reads as:

    %?      if
    X       X to be tested
    ?       then (%X is non-zero)
    %X      print %X
    &       else (%X is zero)
    space   a space
    ?       end of "if"

so this prints the number of attachments
unless it is "0" (no attachments) -
then it will simply print a "space".

when the number of attachments is more than 9,
well, then it will use two characters.
in that case you will spot it easily. ;-)

you can "limit" your messages to "~X3-",
ie having at least three attachments.

my INBOX has 5,000 mails now..
one with 7, one with 8 attachments - and
one has 15 and another 17 attachments. :-O
those two big ones really stand out now.

unfortunately, the sort commands (o for sort-mailbox and
O for sort-reverse) cannot sort by number of attachments.
