Code:

abc,12345
pqr,51223
mno,72121
stu,34567
aaa,12345
pqp,11224
plm,72121
zxy,88888
fgh,12345
jkl,88888
$ awk -F, 'NR==FNR{a[$2]++;next}{print $0 "," a[$2]}' file file
abc,12345,3
pqr,51223,1
mno,72121,2
stu,34567,1
aaa,12345,3
pqp,11224,1
plm,72121,2
zxy,88888,2
fgh,12345,3
jkl,88888,2

Am I missing something?

lire::count

Count(3pm)						  LogReport's Lire Documentation						Count(3pm)

NAME

       Lire::Count - Lire class that implements the count operator

SYNOPSIS

	use Lire::Count

DESCRIPTION

       Class that implements the count operator. This operator counts the number of DLF records in the current group.

       If the fields attribute is set, the count statistics will be equals to the number of different values present in the fields specified by
       that attribute.

       Its also possible to express the count as a ratio of the total count for the group or table.

METHODS

   new( %params )
       Creates a new Lire::Count object. In addition to the values supported by its parents, the fields and ratio attributes will be initialized
       to the values specified in the %params argument.

   fields( [$new_fields] )
       Returns the fields for which we are counting the different values.  This a reference to an array of DLF field names.

       If the $new_fields parameter is set, it will be used as the new $fields value. It must be an array reference and should only contains valid
       field names for the current report specification's schema.

   ratio([$new_ratio])
       Returns how the count will be expressed. This can one of three possible values:

       none
	   Default. The absolute count will be used.

       group
	   The count will be expressed as a percentage of the group's count.

       table
	   The count will be expressed as a percentage of the table's total count.
