Even with ERE, you need to run it twice, perhaps conditionally if the first hits, as you used both start and end field '|'. Otherwise, you miss the following adjacent fields on a line like: "123.|456."

You can add pipes to both ends for the substitute and then remove them:
Code:
sed '
  s/.*/|&|/
  s/\(|[0-9]\{1,99\}\)\.|/\1|/g
  t again
  b end
  :again
  s/\(|[0-9]\{1,99\}\)\.|/\1|/g
  :end
  s/^|//
  s/|$//
 ' in_file

I could have removed both added pipes with one substitute "s/^|\(.*\)|$/\1/" but these back references are a bit slower, in my experience, so I avoid them where possible.

Two passes can be avoided if a less careful pattern is sought, like "s/\([0-9]\).|/\1/", as it encompasses only one pipe. It mangles any non-numeric field with a trailing numer and dot, like "123|The field count of this line is 3.|xyz".

NAME
field_just, set_field_just -- form library LIBRARY
Curses Form Library (libform, -lform) SYNOPSIS
#include <form.h> int field_just(FIELD *field); int set_field_just(FIELD *field, int justification); DESCRIPTION
Field justification is only applied to static fields, a dynamic field will not be justified. The default justification for a field is NO_JUSTIFICATION. The field_just() will return the current justification value of the given field and the justification may be set by call- ing the set_field_just() function. PARAMETERS
The following are the valid justifications for a field: NO_JUSTIFICATION No justification is to be applied to the field. In practice, this is the same as JUSTIFY_LEFT. JUSTIFY_RIGHT The field will be right justified. That is, the end of each line will be butted up against the right hand side of the field. JUSTIFY_LEFT The field will be left justified. That is, the start of each line will be butted up against the left hand side of the field. JUSTIFY_CENTER The field will be centre justified, padding will be applied to either end of the line to make the line centred in the field. RETURN VALUES
The functions will return one of the following error values: E_OK The function was successful. E_CURRENT The field specified is the currently active one on the form. E_BAD_ARGUMENT A bad argument was passed to the function. SEE ALSO
curses(3), forms(3) NOTES
The header <form.h> automatically includes both <curses.h> and <eti.h>. BSD
