I agree that this may be a problem in dash.  Anyway, there's a simple
workaround, the only problem is this line

 for base in $((cd $home/series/ && ls -d *) | sort -rnt- -k 2); do

and to make it the parser easier, simply put a space between the two '(':

 for base in $( (cd $home/series/ && ls -d *) | sort -rnt- -k 2); do

With some good will you can read this from:

  If the command substitution consists of a single subshell, such as:
  
  $( (command) )
  
  a conforming application shall separate the "$(" and '(' into two tokens
  (that is, separate them with white space). This is required to avoid any
  ambiguities with arithmetic expansion.
