Nope. You'll have to transpose the coefficient entries.
e.g.
Al = {
  AtomicNumber = 13
  Orbital = {
    AngularMomentum = 0
    Occupation = 2.000000
    Cutoff = 10.0
    Exponents = {
       13.00000000 4.41588000 1.50000000
    }
    Coefficients = {
-4.09243550e+00
-3.94130950e+01
-1.30495860e+02
2.65911590e+01
-2.71718630e+01
7.45180650e+01
-1.50484190e+01
1.34738100e+01
-1.25288290e+00
 }
  }

Please find attached the corrected wfc.matsci-0-3.hsd for all elements
ofthe  matsci-set.

Cheers, Johannes
