Try this awk script which sorts each line and removes the dups...
Code:
awk '{
   n = split($0,a," ")
   for (i=1; i<n; i++)
     for (j=1; j<=n-i; j++)
       if (a[j] > a[j+1]) {
          t=a[j]
          a[j]=a[j+1]
          a[j+1]=t
       }
   for (i=1; i<=n; i++)
       v=sprintf("%s",v?v""a[i]:a[i])
   if (v in x); else print $0
   x[v]=v; v=""
}' file

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
