here's an alternative in Python:
Code:
def transpose(matrix):        
        return [[matrix[y][x] for y in range(len(matrix))]for x in range(len(matrix[0]))]


all = open("input.txt").readlines()
lookupstring = ['MANDT', 'SERSCHA','SERAIL' , 'SEREX', 'EQTYP', 'BSTVP']
listing = [ i.split() for i in all ] 
results =  transpose(listing)
final= [ r for items in lookupstring for r in results if items == r[0] ]
for i in transpose(final):
        print ','.join(i)

Input:
Code:
MANDT SERAIL EQTYP SERSCHA SEREX BSTVP
510   hsgdfs 44    sercha  sex1  bst233
510   bg     89    fg      23    98
510   gh     89    we      sew   mn

Output:
Code:
/home>python test.py
MANDT,SERSCHA,SERAIL,SEREX,EQTYP,BSTVP
510,sercha,hsgdfs,sex1,44,bst233
510,fg,bg,23,89,98
510,we,gh,sew,89,mn
