file="$1"; shift

awk -v cols="$*" '
BEGIN{
	split(cols,C)
	OFS=FS="\t"
	getline
	split($0,H)
	for(c in C){
		for(h in H){
			if(C[c]==H[h])F[i++]=h
		}
		l=l C[c] OFS
	}
	print l
}
{ l="";for(f in F){l=l $F[f] OFS}print l }

' "$file"

Here is a more condensed version of the same script, it displays the header with no extra code:
Code:
#!/bin/sh

file="$1"; shift

awk -v c="$*" '
BEGIN{split(c,C);OFS=FS="\t"}
NR==1{
  for(c in C){
    f=0;while(f++<NF){
      if(C[c]==$f)F[i++]=f
}}}
{l="";for(f in F)l=l $F[f] OFS}
$0=l' "$file"

exit 0

*feels like I miss something to make this code simpler, but I can't figure out :p*
