That's because it's not a text spanner - it's a text script. You could 
use the
extra-offset property to fiddle the horizontal position - the following 
produces
an approximately centered (p) for me:

\score {
 \context Staff {
   \notes \relative c' {
   \property Voice.TextScript \override #'extra-offset = #'(-0.7 . 0)
   c1_#'(columns (large "(") (dynamic "p") (large ")"))
   }
 }
}

To create a text spanner see Expressive marks->Text spanners in the manual.
