Surely you must have overlooked using PaddedForm[] like this?

In[1]:= ToString[PaddedForm[#, {6, 4}]]& /@ {1., 1.39281, 1.31}

Out[1]= {  1.0000,   1.3928,   1.3100}

In[2]:= Export["testme.dat", %, "List"]

Out[2]= testme.dat

In[3]:= !! "testme.dat"
  1.0000
  1.3928
  1.3100

ToString[] is used to capture the textual representation emitted
by PaddedForm[].
