Enumerating a list with multiple lines labels

Question

I am making a list of problems for a contest that should look like this:

Problem 1. Some text 
5 points   As the text continues it stays aligned
           to this
           |<--
           |<--
            Invisible line
Problem 2. More text
1 point    also aligned

I want to use an enumerate-like environment, like

\newenvironment{questions}{
\begin{list}{ 
    \bfseries\upshape\arabic{qcounter}.
}{
    \renewcommand{\makelabel}[1]{%
\textbf{\refstepcounter{qcounter}\arabic{qcounter}##1.}}%
    \usecounter{qcounter}
    \setlength{\labelwidth}{2.5em}
    \setlength{\labelsep}{0.5em}
\setlength{\leftmargin}{\labelwidth+\labelsep}
        \setlength{\itemsep}{2pt}
        \setlength{\listparindent}{1em}
    \setlength{\parsep}{1pt}
    \setlength{\topsep}{6pt}
} 
}{    
    \end{list}
}

I have changed renewing of makelabel to

\renewcommand{\makelabel}[1]{%
\textbf{\refstepcounter{qcounter}Problem \arabic{qcounter}##1.}\\##1 points}

but it didn't work. I also tried putting it into minipage, but the text of the item looks strange after it.

I also want to give item to arguments: number of points and the ending or the word points, like point##2, because I write in russian and the ending of the word changes strongly, depending on the number.

Is there any option I can do such a list?

Answer 1

\usepackage{calc}
\newcounter{qcounter}
% Item parameter is number of points.
% See The LaTeX Companion, Second Edition, page 150.
\newcommand{\questionlabel}[1]{%
  \refstepcounter{qcounter}\raisebox{0pt}[1ex][0pt]%
  {\makebox[\labelwidth][l]%
    {\parbox[t]{\labelwidth}%
      {\hspace{0pt}\textbf{Problem \arabic{qcounter}}\\#1 points}}}}

\newenvironment{questions}
{\begin{list}{}{\let\makelabel\questionlabel
    \setlength{\itemsep}{2pt}
    \setlength{\listparindent}{1em}
