awk weirdness on DU

I've trying to run a program containing a rather complex awk script (I
didn't write it, so I can't really explain how it's doing what it does).
Said script works on AIX, HPUX, and IRIX, but not on DU (3.2G _or_ 4.0+).
Are there any known differences between Digital's awk and everyone else's?
Is POSIX biting me again?

The awk piece is:

     awk 'BEGIN { FS="#" ; RS=">" }
           { i=0 ; printf "%s", $1
             for (j=3; j<NF; j+=2)
               { for (k=i; k>0; k--)
                   { if ($j > a[k]) break
                     a[k+1]=a[k] ; n[k+1]=n[k] }
                 i++ ; k++ ; a[k]=$j ; n[k]=$(j+1) }
             for (j=1; j<=i; j++) printf " %s %s", a[j], n[j]
             printf "\n" }'

The file it's processesing is of the form

>northstar.dartmouth.edu #Dartmouth College, Project Northstar
        129.170.16.43 #cygnusx1.dartmouth.edu
        129.170.16.205 #beehive.dartmouth.edu
        129.170.24.37 #andromeda.dartmouth.edu
        129.170.24.115 #horsehead.dartmouth.edu

Expected output is

        northstar.dartmouth.edu 129.170.16.205 beehive.dartmouth.edu 129.170.16.43 cygnusx1.dartmouth.edu 129.170.24.115 horsehead.dartmouth.edu 129.170.24.37 andromeda.dartmouth.edu

but DU gives me


        northstar.dartmouth.edu andromeda.dartmouth.edu
        129.170.24.115 horsehead.dartmouth.edu
         cygnusx1.dartmouth.edu
        129.170.16.205 beehive.dartmouth.edu
        129.170.24.37

Any ideas?

Thanks.
