Not sure how to reconcile your written spec and the sampe output. Do you mean you want to insert a field by copying tolower($1) between $1 and $2? And, the count info should be the number of lines between <s> and </s>?

Assuming above thoughts to be true, try
Code:
awk '
        {if ($1 ~ "<\/?s>") ST = NR
         else   {$1=$1 OFS tolower($1)
                 $3=NR-ST
                }
        }

kiconv

KICONV(3)						   BSD Library Functions Manual 						 KICONV(3)

NAME

     kiconv_add_xlat16_cspair, kiconv_add_xlat16_cspairs, kiconv_add_xlat16_table -- kernel side iconv library

LIBRARY

     Kernel side iconv library (libkiconv, -lkiconv)

SYNOPSIS

     #include <sys/iconv.h>

     int
     kiconv_add_xlat16_cspair(const char *tocode, const char *fromcode, int flag);

     int
     kiconv_add_xlat16_cspairs(const char *foreigncode, const char *localcode);

     int
     kiconv_add_xlat16_table(const char *tocode, const char *fromcode, const void *data, int datalen);

DESCRIPTION

     The kiconv library provides multi-byte character conversion tables for kernel side iconv service.

     The kiconv_add_xlat16_cspair() function defines a conversion table using iconv(3) between fromcode charset and tocode charset.  You can spec-
     ify flag to determine if tolower(3) / toupper(3) conversion is included in the table.  The flag has following values.

     KICONV_LOWER
     KICONV_FROM_LOWER	It generates a tolower table in addition to a character conversion table.  The difference between two is tolower tocode or
			tolower fromcode.
     KICONV_UPPER
     KICONV_FROM_UPPER	It generates a toupper table in addition to a character conversion table.  The difference between two is toupper tocode or
			toupper fromcode.

     A tolower/toupper conversion is limited to single-byte characters.

     The kiconv_add_xlat16_cspairs() function defines two conversion tables which are from localcode to foreigncode and from foreigncode to
     localcode.  These conversion tables also contain both tolower and toupper tables.

     The kiconv_add_xlat16_table() function defines a conversion table directly pointed by data whose length is datalen, not using iconv(3).
