The tag code moved out of Interpolate.pm and into 
VENDROOT/code/SystemTag/error.coretag.

The section relevant to your needs:
       if($opt->{std_label}) {
                # store the error label in user's session for later
                # possible use in [error show_label=1] calls
                $Vend::Session->{errorlabels}{$var} = $opt->{std_label};
                if($text) {
                        # do nothing
                }
                elsif(defined $::Variable->{MV_ERROR_STD_LABEL}) {
                        $text = $::Variable->{MV_ERROR_STD_LABEL};
                }
                else {
                        $text = <<EOF;
<FONT COLOR=RED>{LABEL} <SMALL><I>(%s)</I></SMALL></FONT>
[else]{REQUIRED <B>}{LABEL}{REQUIRED </B>}[/else]
EOF
                }
                $text =~ s/{LABEL}/$opt->{std_label}/g;
                $text =~ s/{REQUIRED\s+([^}]*)}/$opt->{required} ? $1 : 
''/ge;
                $err =~ s/\s+$//;
        }
        $text = '' unless defined $text;
        $text .= '%s' unless $text =~ /\%s/;
        $text = pull_else($text, $found_error);
        return sprintf($text, $err);

As you can see, you may provide a template in the variable 
MV_ERROR_STD_LABEL, or you can provide a template via the "text" 
attribute when you call the tag:
[error name=some_field std_label="Some Field" text=|<span 
class="error_text">{LABEL}: You blew it!  Here's why -- (%s)</span>
[else]<span class="label{REQUIRED _required}">{LABEL}[/else]
|]

The label you give to the error tag goes in at {LABEL}, the error 
message goes in at (%s) when appropriate, and {REQUIRED <some_content>} 
is replaced by <some_content> if the "required" attribute is set.  The 
[else]...[/else] block is used when no error is found, while the other 
portion is used when an error is present.

In your specific case, you would set up the else portion as:
[else]{LABEL} {REQUIRED *}[/else]

Fortunately there's no need to hack the core to do this; just set up 
that catalog variable if you want this to be consistent through your 
catalog.
