I don't get that kind of output with ls -l but assuming you do, the following ought to work.

Code:
ls -l | awk '{ tot[$2] += $1 } END { for (t in tot) printf "%s\t%i\n", t, tot[t] }'

Requesting ls to sort the output is unnecessary, if you require chronological output order, some additional tricks will be needed. The array loop in awk for (x in y) traverses the keys of y in unpredictable order.

Also the sample output you posted doesn't seem to agree with the input. I get the following

Code:
Feb     4593
May     1332
Apr     3131
Mar     2565

Did I misunderstand your requirement, or is the sample output wrong? Looks like you accidentally summed Mar and May into the same category.

tau2otf

TAU2OTF(1)							       Tools								TAU2OTF(1)

NAME

       tau2otf - convert TAU tracefiles to OTF tracefiles for Vampir/VNG

SYNOPSIS

       tau2otf [-n streams] [-nomessage] [-v]

DESCRIPTION

       This program is generated when TAU is configured with the -otf=<otf_dir> option. The tau2otf trace converter takes a TAU formatted
       tracefile (*.trc) and a TAU event description file (*.edf) and produces an output trace file in the Open Trace Format (OTF). The user may
       specify the number of output streams for OTF. The input files and output file must be specified in that order. TAU traces should be merged
       using tau_merge prior to conversion.

OPTIONS

       -n streams Specifies the number of output streams (default is 1).  -nomessage Suppresses printing of message information in the trace.  -v
       Verbose mode sends trace event descriptions to the standard output as they are converted.

EXAMPLES

       The program must be run with the tau trace, tau event and otf output files specified in the command line in that order. Any additional
       arguments follow. The following will produced an OTF file, a pp.otf and other related event and definition files, from the TAU trace and
       event files merged.trc and tau.edf trace file:

       tau2otf merged.trc tau.edf app.otf
