I have not been successful in converting the following If Do routine,  
to a routine using the If Map function.

Matrix
a={{1,5,10},{25,0,2000},{55,5,2001}}

If Do Routine that works
y=0;
Do[y=y+1;x=0;
  Do[x=x+1;
   a[[x,y]]=
     If[a[[x,y]]<10,(StringJoin[ToString[0],ToString[a[[x,y]]]]),a[[x,y]]],
   {Length[a]}],
  {Length[Transpose[a]]}]

If Map Routine that does not work

If[# < 10, (StringJoin[ToString[0], ToString[#]]), # ] & /@ a

Please help.
Thanks,

Benedetto Bongiorno
